A second monoclinic polymorph of {2,6-bis[(2,4,5-trifluoro-phen-yl)imino-meth-yl]pyridine-?N,N',N''}dichloridonickel(II).

ABSTRACT: The asymmetric unit of the title compound, [NiCl(2)(C(19)H(9)F(6)N(3))], contains one half-mol-ecule residing on a crystallographic twofold rotation axis. The title compound crystallizes in space group C2/c while the previously reported polymorph was reported in P2(1)/c [Baldovino-Pantaleón et al. (2006 ?). Adv. Synth. Catal.348, 236-242]. The Ni(2+) ion exhibits a penta-coordinate distorted trigonal-bipyramidal NiCl(2)N(3) geometry, with two Cl atoms in the equatorial plane. In the crystal, mol-ecules are linked by inter-molecular C-F?? [F?centroid = 2.9676?(14)?Å] inter-actions.

Bis[2-(hy-droxy-imino-meth-yl)phenolato]nickel(II): a second monoclinic polymorph.

Project description:The title compound, [Ni(C(7)H(6)NO(2))(2)], (I), is a second monoclinic polymorph of the compound, (II), reported by Srivastava et al. [Acta Cryst. (1967), 22, 922] and Mereiter [Private communication (2002) CCDC refcode NISALO01]. The bond lengths and angles are similar in both structures. The mol-ecule in both structures lies on a crystallographic inversion center and both have an inter-nal hydrogen bond. The title compound crystallizes in the space group P2(1)/c (Z = 2), whereas compound (II) is in the space group P2(1)/n (Z = 2) with a similar cell volume but different cell parameters. In both polymorphs, mol-ecules are arranged in the layers but in contrast to the previously published compound (II) where the dihedral angle between the layers is 86.3°, in the title polymorph the same dihedral angle is 29.4°. The structure of (I) is stabilized by strong intra-molecular O-H⋯O hydrogen bonding between the O-H group and the phenolate O atom.

N,N'-Bis[4-(trifluoro-meth-yl)phen-yl]pyridine-2,6-dicarboxamide.

Project description:In the title mol-ecule, C(21)H(13)F(6)N(3)O(2), the pyridine ring forms dihedral angles of 1.7?(1) and 5.2?(1)° with the two benzene rings. In the crystal structure, inter-molecular N-H?O hydrogen bonds and ??? inter-actions [centroid-centroid distance of 3.628?(3)?Å between aromatic rings] link mol-ecules into stacks along the c axis. The two trifluoro-methyl groups are each rotationally disordered between two orientations, with occupancy ratios of 0.58?(1):0.42?(1) and 0.55?(1):0.45?(1).

2-[(1,3-Benzo-thia-zol-2-yl)imino-meth-yl]-6-meth-oxy-phenol: a new monoclinic polymorph.

Project description:The title compound, C15H12N2O2S, is a P21/c polymorph of a previously reported P21/n polymorph [Büyükgüngör et al. (2004 ?). Acta Cryst. E60, o1414-o1416]. The dihedral angle between the benzo-thia-zole (r.m.s. deviation = 0.010?Å) and the benzene ring of 7.86?(6)° compares with 10.76?(10)° in the literature structure. The meth-oxy substituent is almost coplanar with the benzene ring to which it is attached [C-O-C-C torsion angle = 178.31?(14)°] and the conformation about the imine bond [1.287?(2)?Å] is E. There is an intra-molecular O-H?N hydrogen bond and the hy-droxy O and thio-ether S atoms are syn. In the crystal, columns are formed along the b axis as centrosymmetric dimeric aggregates, mediated by C-H?O inter-actions and linked by ?-? inter-actions between the thia-zole and benzene rings [centroid-to-centroid distance = 3.8256?(10)?Å].

A second monoclinic polymorph of di-?-chlorido-bis-(chlorido{2-[(4-ethyl-phen-yl)imino-meth-yl]pyridine-?²N,N'}copper(II)).

Project description:The title compound, [Cu?Cl?(C??H??N?)?], is a new polymorph of a previously reported compound [Dehghanpour et al. (2011 ?). Acta Cryst. E67, m1296]. The current polymorph was obtained from an acetonitrile solution of the title compound. Like the first polymorph, it is monoclinic (space group P2?/c). The unique Cu(II) ion in the title centrosymmetric dinuclear complex is in a distorted trigonal-bipyramidal coordination environment formed by the bis--chelating N-heterocyclic ligand, two bridging Cl ligands and one terminal Cl ligand. In the crystal, weak C-H?Cl hydrogen bonds are observed in addition to ?-? stacking inter-actions, with a centroid-centroid distance of 3.6597?(18)?Å.

Dichlorido{2-[(2,6-dimethyl-phen-yl)imino-meth-yl]pyridine-?N,N'}zinc.

Project description:In the asymmetric unit of the title compound, [ZnCl(2)(C(14)H(14)N(2))], the central Zn(II) ion is four-coordinated in a distorted tetra-hedral environment by two N atoms of the ligand 2-[(2,6-dimethyl-phen-yl)imino-meth-yl]pyridine and two chloride anions. In the crystal, adjacent mol-ecules are connected through C-H?Cl hydrogen bonds between a C-H group of the ligand and a Cl(-) anion, leading to a chain-like structure along the b direction.

2,6-Bis(trifluoro-meth-yl)benzoic acid.

Project description:The title compound, C(9)H(4)F(6)O(2), contains two mol-ecules in the asymmetric unit, one of which exhibits disorder in both of its trifluoro-methyl groups. The dihedral angles between the benzene ring and the carboxyl group are 71.5?(2) and 99.3?(2)° in the two independent mol-ecules. The compound exhibits a catemeric structure resulting from inter-molecular O-H?O hydrogen bonding between the carboxyl groups.

A new polymorph of 2,6-bis-(trifluoro-meth-yl)benzoic acid.

Project description:The asymmetric unit of a second polymorph of the title compound, C(9)H(4)F(6)O(2), contains five independent mol-ecules, which form hydrogen-bonded O-H?O dimers about inversion centers. The most significant structural difference between this structure and that of the first polymorph [Tobin & Masuda (2009 ?). Acta Cryst. E65, o1217] is the hydrogen-bonded, dimeric orientation of the carb-oxy-lic acid functionalities.

Second monoclinic polymorph of 4-[(1H-benzimidazol-1-yl)meth-yl]benzoic acid.

Project description:Recently, we reported the first monoclinic [Kuai & Cheng (2011). Acta Cryst., E67, o2787] and the ortho-rhom-bic polymorph [Kuai & Cheng (2011). Acta Cryst., E67, o3014] of the title compound, C(15)H(12)N(2)O(2). Another monoclinic polymorph was obtained accidentally by the hydro-thermal reaction of the title compound with manganese chloride in the presence of potassium hydroxide at 413?K. The asymmetric unit consists of four independent mol-ecules. In the crystal, O-H?N hydrogen bonds link the independent mol-ecules into four separate chains parallel to the b axis.

2-Methyl-6-[2-(trifluoro-meth-yl)phenyl-imino-meth-yl]phenol.

Project description:The title compound, C(15)H(12)F(3)NO, is a Schiff base which adopts the phenol-imine tautomeric form in the solid state. The dihedral angle between the aromatic rings is 38.79?(5)°. The mol-ecular structure is stabilized by an intra-molecular O-H?N hydrogen bond, which generates an S(6) ring. In addition, there is an intra-molecular short C-H?F contact.

2,6-Bis(bromo-meth-yl)pyridine.

Project description:In the title mol-ecule, C7H7Br2N, the C-Br vectors of the bromo-methyl groups extend to opposite sides of the pyridine ring and are oriented nearly perpendicular to its plane. In the crystal, the mol-ecules related by a c-glide-plane operation are arranged into stacks along the c axis, with centroid-centroid distances between neighboring aromatic rings of 3.778?(2)?Å. A short Br?Br contact of 3.6025?(11)?Å is observed within a pair of inversion-related mol-ecules.
