Deskripsi
In the title compound, [CdCl(NCS)(C9H8N2)]n, the CdII 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 CdII 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 (10overline{1}). Weak intermolecular C—H...Cl hydrogen-bonding interactions help to consolidate the crystal packing.
