4,5-Dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride-1,10-phenanthroline (1/1).

ABSTRACT: In the crystal structure of the title 1:1 adduct, C(12)H(8)N(2)·C(14)H(6)O(7), the carboxyl groups are involved in inter-molecular O-H?O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further linked by inter-molecular O-H?N hydrogen bonds. C-H?O inter-actions also occur between the 1,10-phenanthroline (phen) and 4,5-dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride (H(2)NTC) mol-ecules. In addition, the crystal structure exhibits ?-? inter-actions of the phen?phen and H(2)NTC?H(2)NTC types with centroid-centroid distances of 3.579?(3) and 3.774?(3)?Å, respectively.

In the crystal structure of the title 1:1 adduct, C(12)H(8)N(2)·C(14)H(6)O(7), the carboxyl groups are involved in inter-molecular O-H⋯O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers. These dimers are further linked by inter-molecular O-H⋯N hydrogen bonds. C-H⋯O inter-actions also occur between the 1,10-phenanthroline (phen) and 4,5-dicarb-oxy-naphthalene-1,8-dicarb-oxy-lic anhydride (H(2)NTC) mol-ecules. In addition, the crystal structure exhibits π-π inter-actions of th ...[more]

Project description:A new type of naphthalene-1,8-dicarb-oxy-lic anhydride, C(12)H(6)O(3), was synthesized hydro-thermally. Unlike the two previously reported polymorphs, which crystallize in the ortho-rhom-bic space groups P2(1)2(1)2(1) [Shok et al. (1971). Kristallografiya, 16, 500-502; Grigor'eva & Chetkina (1975). Kristallografiya, 20, 1289-1290] and Pbca [Shok & Gol'der (1970). Zh. Strukt. Khim.11, 939-940], this present structure crystallizes in the monoclinic space group P2(1)/c. In this structure, the planar [total puckering amplitude Q = 0.0362?(15)] mol-ecules lie parallel to each other along the a axis.

Crystal structure of <i>N</i>,<i>N</i>'-bis-[3-(methyl-sulfan-yl)prop-yl]-1,8:4,5-naphthalene-tetra-carb-oxy-lic di-imide.

Project description:The title compound, C22H22N2O4S2, was synthesized by the reaction of 1,4,5,8-naphthalene-tetra-carb-oxy-lic dianhydride with 3-(methyl-sulfan-yl)propyl-amine. The whole mol-ecule is generated by an inversion operation of the asymmetric unit. This mol-ecule has an anti form with the terminal methyl-thio-propyl groups above and below the aromatic di-imide plane, where four intra-molecular C-H⋯O and C-H⋯S hydrogen bonds are present and the O⋯H⋯S angle is 100.8°. DFT calculations revealed slight differences between the solid state and gas phase structures. In the crystal, C-H⋯O and C-H⋯S hydrogen bonds link the mol-ecules into chains along the [2 direction. adjacent chains are inter-connected by π-π inter-actions, forming a two-dimensional network parallel to the (001) plane. Each two-dimensional layer is further packed in an ABAB sequence along the c-axis direction. Hirshfeld surface analysis shows that van der Waals inter-actions make important contributions to the inter-molecular contacts. The most important contacts found in the Hirshfeld surface analysis are H⋯H (44.2%), H⋯O/O⋯H (18.2%), H⋯C/C⋯H (14.4%), and H⋯S/S⋯H (10.2%).

5H-Imidazo[4,5-f][1,10]phenanthroline.

Project description:The title mol-ecule, C(13)H(8)N(4), is is essentially planar [r.m.s. deviation for all non-H atoms = 0.025?(3)?Å]. In the crystal, mol-ecules are connected through one weak bifurcated N-H?(N,N) hydrogen bond and three ?-? stacking inter-actions between pyridine and imidazole rings [centroid-centroid distance = 3.631?(8)?Å] and between pyridine and benzene rings [centroid-centroid distances = 3.675?(5) and 3.666?(2)?Å].

Tris(1,10-phenanthroline)cadmium 3,3'-dicarb-oxy-4,4'-diazenedi-yl-dibenzoate-4,4'-diazenediyldiphthalic acid-methanol (1/0.5/1).

Project description:In the title compoud, [Cd(C(12)H(8)N(2))(3)](C(16)H(8)N(2)O(8))·0.5C(16)H(10)N(2)O(8)·CH(3)OH, the Cd(II) atom has a distorted octa-hedral coordination formed by six N atoms from three separate phenanthroline ligands. One of the 4,4'-diazenediyldiphthalic acid mol-ecules is arranged around an inversion center and possesses two -COOH groups, while the other is partially deprotonated and is a dianion for charge balance. It can be noted that, in the undeprotonated acid, the -COOH groups are disordered over two positions by rotation around the C-C bond linking the -COOH group to the phenyl ring. Surprisingly, the H atom is not involved in the disorder. In the dianion, the remaining H atom is located between the two COO groups. These deprotonated and undeprotonated mol-ecules are linked by O-H?O hydrogen bonds, forming a chain developing parallel to the [111] direction. The methanol solvent molecule is highly disordered; it was not considered in the final model by elimination of its contribution from the intensity data.

Crystal structure of a binuclear nickel(II) complex constructed of 1H-imidazo[4,5-f][1,10]phenanthroline and doubly deprotonated benzene-1,3,5-tri-carb-oxy-lic acid.

Project description:The title complex, [Ni2(C9H4O6)2(C13H8N4)2(H2O)4]·2H2O, bis-(?-5-carb-oxy-benzene-1,3-di-carboxyl-ato-?(2) O (1):O (1'))bis-[di-aqua(1H-imidazo[4,5-f][1,10]phenanthroline-?(2) N (7),N (8))nickel(II)] di-hydrate, was obtained under solvothermal conditions by the reaction of benzene-1,3,5-tricarboxylic acid (H3BTC) with Ni(NO3)2 in the presence of 1H-imidazo[4,5-f][1,10]phenanthroline (IP). The crystal has triclinic (P-1) symmetry with a centrosymmetric binuclear nickel(II) cluster. The Ni(II) atom is coordinated by two N atoms from a chelating 1H-imidazo[4,5-f][1,10]phenanthroline ligand, two carboxyl-ate O atoms from two 5-carb-oxy-benzene-1,3-di-carboxyl-ate ligands and two water mol-ecules in a slightly distorted octa-hedral geometry. Two carboxyl-ate groups bridge two Ni(II) cations, forming the binuclear complex. Extensive N-H?O, O-H?O and O-H?N hydrogen bonding is present in the crystal structure, forming a three-dimensional supermolecular framework. Weak ?-? stacking is observed between parallel HBTC(2-) and IP ring systems, the face-to-face separation being 3.695?(2)?Å.
