A new cadmium–thiocyanate complex, namely catena ‐poly[1‐carboxymethyl‐4‐(dimethylamino)pyridinium [cadmium(II)‐tri‐μ‐thiocyanato‐κ 4 N : S ;κ 2 S : N ] [[[4‐(dimethylamino)pyridinium‐1‐acetate‐κ 2 O , O ′]cadmium(II)]‐di‐μ‐thiocyanato‐κ 2 N : S ;κ 2 S : N ]], {(C 9 H 13 N 2 O 2 )[Cd(NCS) 3 ][Cd(NCS) 2 (C 9 H 12 N 2 O 2 )]} n , was synthesized by the reaction of 4‐(dimethylamino)pyridinium‐1‐acetate, cadmium nitrate tetrahydrate and potassium thiocyanide in aqueous solution. In the crystal structure, two types of Cd II atoms are observed in distorted octahedral coordination environments. One type of Cd II atom is coordinated by two O atoms from the carboxylate group of the 4‐(dimethylamino)pyridinium‐1‐acetate ligand and by two N atoms and two S atoms from four different thiocyanate ligands, while the second type of Cd II atom is coordinated by three N atoms and three S atoms from six different thiocyanate ligands. Neighbouring Cd II atoms are linked by thiocyanate bridges to form a one‐dimensional zigzag chain and a one‐dimensional coordination polymer. Hydrogen‐bond interactions are involved in the formation of the supramolecular network.
