catena-Poly[[(8-amino­quinoline-κ²N,N′)cadmium]-di-μ-thio­cyanato-κ²N:S;κ²S:N-[(8-amino­quinoline-κ²N,N′)cadmium]-di-μ-chlorido]

In the title compound, [CdCl(NCS)(C₉H₈N₂)]_n, the Cd^II atom is in a distorted octa­hedral coordination environment defined by two chloride anions, two N atoms from an 8-amino­quinoline ligand, one N atom from one thio­cyanate anion and one S atom from a symmetry-related thio­cyanate anion. Two Cd^II atoms are bridged by two chloride anions, forming an inversion-related Cd₂Cl₂ unit; these units are further linked through thio­cyanate anions, leading to a chain structure extending parallel to [010]. Weak π–π stacking inter­actions with centroid–centroid distances of 3.430 (4) Å and an inter­planar separation of 3.390 (3) Å between the pyridine and benzene rings link the chains into a two-dimensional network parallel to (10). Weak inter­molecular C—H...Cl hydrogen-bonding inter­actions help to consolidate the crystal packing.

2,6-Dichloro-N-(4-chloro­phen­yl)benzamide

In the title compound, C₁₃H₈Cl₃NO, the dihedral angle between the benzene rings is 63.2 (2)°. In the crystal, N—H...O hydrogen bonds link the mol­ecules into C(4) chains propagating in [001]. Weak aromatic π–π stacking also occurs [centroid–centroid separations = 3.759 (3) and 3.776 (3) Å].

2-Chloro-N-[3-cyano-1-(3,4-dichloro­phen­yl)-1H-pyrazol-5-yl]acetamide

In the title compound, C₁₂H₇Cl₃N₄O, the dihedral angle between the pyrazole and benzene rings is 35.6 (3)°. In the crystal, mol­ecules are linked by N—H...O hydrogen bonds generating C(4) chains propagating in [100].

2-Amino-4-(2-chloro­phen­yl)-6-(naph­thalen-1-yl)pyridine-3-carbonitrile

In the title compound, C₂₂H₁₄ClN₃, prepared by a one-pot reaction under microwave irradiation, the dihedral angles between the central pyridine ring and the pendant naphthyl and chloro­benzene ring systems are 49.2 (2) and 58.2 (3)°, respectively. In the crystal, inversion dimers linked by pairs of N—H...N hydrogen bonds generate R₂²(8) loops. The pyridine N atom is the acceptor.
