Gabapentin-lactum-chloranilic acid (1/1).

ABSTRACT: In the title compound, C(9)H(15)NO·C(6)H(2)Cl(2)O(4) [sytematic name: 2-aza-spiro-[4.5]decan-3-one-chloranilic acid (1/1)], the cyclo-hexane ring of the lactam molecule adopts a slightly distorted normal chair conformation and the five-membered 3-aza-spiro ring is in a slightly distorted chair conformation. The dihedral angle between the least-squares planes of the cyclohexane and 3-azaspiro rings is 84.0?(3)°. In the crystal, the chloranilic acid mol-ecule and the gabapentin-lactum mol-ecules are held together by strong inter-molecular N-H?O and O-H?O hydrogen bonds with two bifurcated O acceptor atoms on the chloranilic acid mol-ecule and one on the gabapentin-lactum mol-ecule, each bonding with an inter- and intra-molecular hydrogen bond. The molecules are linked into chains parallel to (011) and propagating along the b axis.

Chloranilic acid: a redetermination at 100?K.

Project description:The crystal structure of chloranilic acid, C(6)H(2)Cl(2)O(4), was first described by Andersen in 1967 [Andersen, E. K. (1967). Acta Cryst. 22, 188-191] at room temperature using visually estimated intensities. Taking into account the importance of the title compound, we have redetermined the structure at 100?(1)?K. The approximately planar mol-ecule [the maximum deviation from the mean plane through the ring is 0.0014?(9)?Å for the ring atoms and 0.029?(3)?Å for the other atoms] occupies a special position, lying across the center of symmetry. In the crystal structure, a two-dimensional hydrogen-bonded network sustained by O-H?O inter-actions runs approximately parallel to [101]. The two-dimensional layers are further packed in a parallel fashion, stabilized by Cl?Cl inter-actions [Cl?Cl = 3.2838?(8)?Å, C-Cl?Cl = 152.96?(6)°].

Crystal structures of two hydrogen-bonded compounds of chloranilic acid–ethyleneurea (1/1) and chloranilic acid–hydantoin (1/2).

Project description:The structures of the hydrogen-bonded 1:1 co-crystal of chloranilic acid (systematic name: 2,5-dichloro-3,6-dihydroxy-1,4-benzoquinone) with ethyleneurea (systematic name: imidazolidin-2-one), C6H2Cl2O4·C3H6N2O, (I), and the 1:2 co-crystal of chloranilic acid with hydantoin (systematic name: imidazolidine-2,4-dione), C6H2Cl2O4·2C3H4N2O2, (II), have been determined at 180?K. In the crystals of both compounds, the base molecules are in the lactam form and no acid–base interaction involving H-atom transfer is observed. The asymmetric unit of (I) consists of two independent half-molecules of chloranilic acid, with each of the acid molecules lying about an inversion centre, and one ethyleneurea molecule. The asymmetric unit of (II) consists of one half-molecule of chloranilic acid, which lies about an inversion centre, and one hydantoin molecule. In the crystal of (I), the acid and base molecules are linked via O—H?O and N—H?O hydrogen bonds, forming an undulating sheet structure parallel to the ab plane. In (II), the base molecules form an inversion dimer via a pair of N—H?O hydrogen bonds, and the base dimers are further linked through another N—H?O hydrogen bond into a layer structure parallel to (01). The acid molecule and the base molecule are linked via an O—H?O hydrogen bond.

Redetermination of pyridine-4-carbonitrile-chloranilic acid (1/1) at 180 K.

Project description:In the crystal structure of the title compound, C(6)H(4)N(2)·C(6)H(2)Cl(2)O(4), two chloranilic acid (systematic name: 2,5-dichloro-3,6-dihydr-oxy-1,4-benzoquinone) mol-ecules are connected by O-H?O hydrogen bonds to form a dimeric unit. The pyridine-4-carbonitrile mol-ecules are linked on both sides of the dimer via N?H?O hydrogen bonds to give a centrosymmetric 2:2 complex of pyridine-4-carbonitrile and chloranilic acid. The H atom in the N?H?O hydrogen bond is disordered over two positions with approximately equal occupancies. The pyridine ring makes a dihedral angle of 61.54?(14)° with the chloranilic acid plane. The 2:2 units are further linked by inter-molecular C-H?O and C-H?Cl hydrogen bonds. This determination presents a siginficantly higher precision crystal structure than the previously published structure [Tomura & Yamasshita (2008 ?). X-ray Struct. Anal. Online, 24, x31-x32].

Pyridine-3-carbonitrile-chloranilic acid-acetonitrile (2/1/2).

Project description:In the crystal structure of the title compound, 2C(6)H(4)N(2)·C(6)H(2)Cl(2)O(4)·2C(2)H(3)N, the two symmetry-related pyridine-3-carbonitrile mol-ecules are linked to either side of a chloranilic acid (systematic name: 2,5-dichloro-3,6-dihydr-oxy-1,4-benzoquinone) mol-ecule via inter-molecular O-H?N hydrogen bonds, giving a centrosymmetric 2:1 unit. The dihedral angle between the pyridine ring and the chloranilic acid plane is 26.71?(6)°. In addition, the two acetonitrile mol-ecules are linked to either side of the 2:1 unit through C-H?N hydrogen bonds, forming a 2:1:2 aggregate. These 2:1:2 aggregates are further linked by weak inter-molecular C-H?N and C-H?O hydrogen bonds, forming a tape along the c axis.

Resonance-stabilized partial proton transfer in hydrogen bonds of incommensurate phenazine-chloranilic acid.

Project description:The co-crystal of phenazine (Phz) and chloranilic acid (H2ca) becomes ferroelectric upon cooling through the loss of inversion symmetry. Further cooling results in the development of an incommensurate ferroelectric phase, followed by a lock-in transition towards a twofold superstructure. Here we present the incommensurately modulated crystal structure of Phz-H2ca at T = 139?K with a symmetry given by the superspace group P2(1)(½ ?(2) ½)0 and ?(2) = 0.5139. The modulation mainly affects the positions of the protons within half of the intermolecular hydrogen bonds that are responsible for the spontaneous polarization in all three low-temperature phases. Evidence for proton transfer in part of the hydrogen bonds is obtained from the correlated dependence on the phase of the modulation of the lengths of bonds involved in resonance stabilization of the acidic anion, and much smaller variations of bond lengths of atoms not involved in the resonance mechanism. Incommensurability is explained as competition between proton transfer favored for single hydrogen bonds on the basis of pKa values and avoiding unfavorable Coulomb repulsion within the lattice of the resulting ionic molecules.

Accessing New Charge-Transfer Complexes by Mechanochemistry: A Tetrathiafulvalene Chloranilic Acid Polymorph Containing Segregated Tetrathiafulvalene Stacks.

Project description:Two polymorphs of tetrathiafulvalene chloranilic acid (TTF-CAH2) have been synthesized by mechanochemistry. The previously known "ionic" polymorph (form I) was prepared by liquid-assisted grinding (LAG) using various highly polar solvents as well as protic but moderately polar solvents, such as alcohols of one to four carbon atoms. A new TTF-CAH2 polymorph (form II) was obtained by LAG and slurry mechanochemistry using aprotic, low-polarity solvents, as well as nonpolar solvents and neat grinding. The crystal structure of the new TTF-CAH2 polymorph was determined from the combined analysis of synchrotron powder X-ray diffraction and neutron powder diffraction data at room temperature. The material displays segregated stacks of TTF and CAH2 molecules. Fourier transform infrared spectroscopy as a function of the temperature (10-300 K) indicates that TTF-CAH2 form II is an electrical semiconductor with a small band gap of ∼0.115 eV (versus ∼0.146 eV for the "ionic" form I), and there is no indication of phase transitions in that temperature interval. The examination of the frequency regions wherein the absorption bands of TTF and TTF+• species occur suggests that TTF-CAH2 form II is most likely a neutral phase.

Crystal structures of two 1:2 dihydrate compounds of chloranilic acid with 2-carb-oxy-pyridine and 2-carb-oxy-quinoline.

Project description:The crystal structure of the 1:2 dihydrate compound of chloranilic acid (systematic name: 2,5-di-chloro-3,6-dihy-droxy-1,4-benzo-quinone) with 2-carb-oxy-pyridine (another common name: picolinic acid; systematic name: pyridine-2-carb-oxy-lic acid), namely, 2C6H5.5NO20.5+·C6HCl2O4-·2H2O, (I), has been determined at 180?K, and the structure of the 1:2 dihydrate compound of chloranilic acid with 2-carb-oxy-quinoline (another common name: quinaldic acid; systematic name: quinoline-2-carb-oxy-lic acid), namely, 2C10H7NO2·C6H2Cl2O4·2H2O, (II), has been redetermined at 200?K. This determination presents a higher precision crystal structure than the previously published structure [Marfo-Owusu & Thompson (2014 ?). X-ray Struct. Anal. Online, 30, 55-56]. Compound (I) was analysed as a disordered structure over two states, viz. salt and co-crystal. The salt is bis-(2-carb-oxy-pyridinium) chloranilate dihydrate, 2C6H6NO2+·C6Cl2O42-·2H2O, and the co-crystal is bis-(pyridinium-2-carboxyl-ate) chloranilic acid dihydrate, 2C6H5NO2·C6H2Cl2O4·2H2O, including zwitterionic 2-carb-oxy-pyridine. In both salt and co-crystal, the water mol-ecule links the chloranilic acid and 2-carb-oxy-pyridine mol-ecules through O-H?O and N-H?O hydrogen bonds. The 2-carb-oxy-pyridine mol-ecules are connected into a head-to-head inversion dimer by a short O-H?O hydrogen bond, in which the H atom is disordered over two positions. Compound (II) is a 1:2 dihydrate co-crystal of chloranilic acid and zwitterionic 2-carb-oxy-quinoline. The water mol-ecule links the chloranilic acid and 2-carb-oxy-quinoline mol-ecules through O-H?O hydrogen bonds. The 2-carb-oxy-quinoline mol-ecules are connected into a head-to-tail inversion dimer by a pair of N-H?O hydrogen bonds.

Crystal structures of three hydrogen-bonded 1:2 compounds of chloranilic acid with 2-pyridone, 3-hy-droxy-pyridine and 4-hyroxypyridine.

Project description:The crystal structures of the 1:2 compounds of chloranilic acid (systematic name: 2,5-di-chloro-3,6-dihy-droxy-1,4-benzo-quinone) with 2-pyridone, 3-hy-droxy-pyridine and 4-hyroxypyridine, namely, bis-(2-pyridone) chloranilic acid, 2C5H5NO·C6H2Cl2O4, (I), bis-(3-hy-droxy-pyridinium) chloranilate, 2C5H6NO+·C6Cl2O42-, (II), and bis-(4-hy-droxy-pyridinium) chloranilate, 2C5H6NO+·C6Cl2O42-, (III), have been determined at 120?K. In the crystal of (I), the base mol-ecule is in the lactam form and no acid-base inter-action involving H-atom transfer is observed. The acid mol-ecule lies on an inversion centre and the asymmetric unit consists of one half-mol-ecule of chloranilic acid and one 2-pyridone mol-ecule, which are linked via a short O-H?O hydrogen bond. 2-Pyridone mol-ecules form a head-to-head dimer via a pair of N-H?O hydrogen bonds, resulting in a tape structure along [201]. In the crystals of (II) and (III), acid-base inter-actions involving H-atom transfer are observed and the divalent cations lie on an inversion centre. The asymmetric unit of (II) consists of one half of a chloranilate anion and one 3-hy-droxy-pyridinium cation, while that of (III) comprises two independent halves of anions and two 4-hy-droxy-pyridinium cations. The primary inter-molecular inter-action in (II) is a bifurcated O-H?(O,O) hydrogen bond between the cation and the anion. The hydrogen-bonded units are further linked via N-H?O hydrogen bonds, forming a layer parallel to the bc plane. In (III), one anion is surrounded by four cations via O-H?O and C-H?O hydrogen bonds, while the other is surrounded by four cations via N-H?O and C-H?Cl hydrogen bonds. These inter-actions link the cations and the anions into a layer parallel to (301).

Gabapentin for smoking cessation.

Project description:We conducted a preliminary proof-of-concept study evaluating gabapentin for the treatment of tobacco dependence.Subjects (N = 80) were randomized to gabapentin (600 mg three times per day or 900 mg three times per day) or placebo. After a 2-week dose titration, the target dose was maintained for 9 weeks and then tapered over 1 week. Follow-up was for 12 weeks after the medication phase.The study had high dropout rates with more than one half of participants in each arm discontinuing study. Gabapentin-treated participants exhibited lower abstinence rates than placebo-treated participants; however, this difference was not significant. Smoking reduction was observed across all treatment arms compared with baseline (p < .01) but did not differ across treatment groups.Although not definitive, our findings suggest that gabapentin administered at these doses with this dosing regimen holds little promise for the treatment of tobacco dependence in a population of smokers seeking treatment.
