4-[(E)-2-(Pyridin-2-yl)ethen-yl]pyridine-terephthalic acid (2/1).

ABSTRACT: The title 2:1 co-crystal, 2C12H10N2·C8H6O4, crystallizes with one mol-ecule of 4-[(E)-2-(pyridin-2-yl)ethen-yl]pyridine (A) and one half-mol-ecule of terephthalic acid (B) in the asymmetric unit. In the crystal, the components are linked through heterodimeric COOH⋯Npyridine synthons, forming linear aggregates of composition -A-B-A-B-. Further linkage through weak C-H⋯O and C-H⋯π inter-actions gives two-dimensional hydrogen-bonded undulating sheets propagating in the [100] and [010] directions. These layers are connected through additional weak C-H⋯O contacts, forming a three-dimensional structure.

4-(1H-Pyrazol-3-yl)pyridine-terephthalic acid-water (2/1/2).

Project description:In the title compound, 2C(8)H(7)N(3)·C(8)H(6)O(4)·2H(2)O, the pyridine and pyrazole rings are approximately coplanar, the dihedral angle between them being 4.69?(9)°. The asymmetric unit consists of half of the terephthalic acid (an inversion centre generates the other half of the mol-ecule), one 4-(1H-pyrazol-3-yl)pyridine (4pp) mol-ecule and one water mol-ecule. In the crystal, two 4pp and one terephthalic acid mol-ecules form a linear three-molecule unit as a result of O-H?N hydrogen bonds. These units are further assembled into a three-dimensional network by two types of hydrogen bonds, viz. O-H?O and N-H?O.

Methyl 6-oxo-4-phenyl-2-[(Z)-2-(pyridin-2-yl)ethen-yl]-1,4,5,6-tetra-hydro-pyridine-3-carboxyl-ate.

Project description:In the title mol-ecule, C20H18N2O3, an intra-molecular N-H⋯O hydrogen bond leads to a cis conformation of the pyridinyl-vinyl fragment. The phenyl and pyridine rings are inclined to one another by 77.3 (1) °. In the crystal, mol-ecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers. The dimers are linked by C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional structure.

2-Amino-benzoic acid-4-(pyridin-4-yl-disulfan-yl)pyridine (1/1).

Project description:The title 1:1 co-crystal, C(7)H(7)NO(2)·C(10)H(8)N(2)S(2), features a highly twisted 4-(pyridin-4-yldisulfan-yl)pyridine mol-ecule [dihedral angle between the pyridine rings = 89.06 (10)°]. A small twist is evident in the 2-amino-benzoic acid mol-ecule, with the C-C-C-O torsion angle being -7.7 (3)°. An N-H⋯O hydrogen bond occurs in the 2-amino-benzoic acid mol-ecule. In the crystal, mol-ecules are linked by O-H⋯N and N-H⋯N hydrogen bonds into a supra-molecular chain along the b axis. These are connected into layers by π-π inter-actions occurring between pyridine rings [centroid-centroid distance = 3.8489 (15) Å]. The layers are connected along the a axis by C-H⋯O contacts. The crystal studied was a racemic twin.

2-Amino-benzoic acid-4-[2-(pyridin-4-yl)eth-yl]pyridine (2/1).

Project description:The asymmetric unit of the title co-crystal, C12H12N2·2C7H7NO2, comprises a centrosymmetric 4-[2-(pyridin-4-yl)eth-yl]pyridine mol-ecule and a 2-amino-benzoic acid mol-ecule in a general position. The acid has a small twist between the carb-oxy-lic acid residue and the ring [dihedral angle = 7.13?(6)°] despite the presence of an intra-molecular N-H?O(carbon-yl) hydrogen bond. Three-mol-ecule aggregates are formed via O-H?N(pyrid-yl) hydrogen bonds, and these are connected into supra-molecular layers in the bc plane by N-H?O(carbon-yl) hydrogen bonds and ?-? inter-actions between pyridine and benzene rings [inter-centroid distance = 3.6332?(9)?Å]. Layers are connected along the a axis by weak ?-? inter-actions between benzene rings [3.9577?(10)?Å].

Diiodidobis{4-[2-(2-methyl-phen-yl)ethen-yl]pyridine-?N}cadmium.

Project description:In the title complex, [CdI(2)(C(14)H(13)N)(2)], the Cd atom lies on a twofold rotation axis that relates the I atom and the 4-(2-methyl-styr-yl)pyridine ligand to their counterparts. Therefore the asymmetric unit contains one crystallographically independent half-mol-ecule. The Cd atom adopts a tetra-hedral coordination geometry, coordinated by two I atoms and two N atoms from the symmetry-related 4-(2-methyl-styr-yl)pyridine ligands.

The equivalent data for mol-ecule B are 0.065 Å, 48.28 (11)° and 61.0 (3)°, respectively. In the crystal, the components are connected by weak N-H⋯N hydrogen bonds, generating [030] C(14) chains of alternating A and B mol-ecules.

Benzoic acid-4-{(1E)-[(E)-2-(pyridin-4-yl-methyl-idene)hydrazin-1-yl-idene]meth-yl}pyridine (2/1).

Project description:In the title co-crystal, C(12)H(10)N(4)·2C(7)H(6)O(2), the complete 4-pyridine-aldazine mol-ecule is generated by a crystallographic centre of inversion. In the crystal, mol-ecules are connected into a three component aggregate via O-H?N hydrogen bonds. As both the benzoic acid [O-C-C-C torsion angle = 174.8?(2)°] and 4-pyridine-aldazine (r.m.s. deviation of the 16 non-H atoms = 0.041?Å) mol-ecules are almost planar, the resulting three-component aggregate is essentially planar. The crystal packing comprises layers of the three-component aggregates of alternating orientation stacked along the b axis; the connections between the mol-ecules are of the types C-H?? and ?-? [pyridine-benzene centroid-centroid distance = 3.787?(4)?Å].
