In the title compound, [CdCl(NCS)(C(9)H(8)N(2))](n), the Cd(II) atom is in a distorted octa-hedral coordination environment defined by two chloride anions, two N atoms from an 8-amino-quinoline ligand, one N atom from one thio-cyanate anion and one S atom from a symmetry-related thio-cyanate anion. Two Cd(II) atoms are bridged by two chloride anions, forming an inversion-related Cd(2)Cl(2) unit; these units are further linked through thio-cyanate anions, leading to a chain structure extending parallel to [010]. Weak π-π stacking inter-actions with centroid-centroid distances of 3.430 (4) Å and an inter-planar separation of 3.390 (3) Å between the pyridine and benzene rings link the chains into a two-dimensional network parallel to (10[Formula: see text]). Weak inter-molecular C-H⋯Cl hydrogen-bonding inter-actions help to consolidate the crystal packing.
