A cadmium–thiocyanate complex, poly[[bis(nicotinic acid‐κ N )di‐μ‐thiocyanato‐κ 2 N : S ;κ 2 S : N ‐cadmium(II)] monohydrate], {[Cd(NCS) 2 (C 6 H 5 NO 2 ) 2 ]·H 2 O} n , was synthesized by the reaction of nicotinic acid, cadmium nitrate tetrahydrate and potassium thiocyanide in aqueous solution. In the crystal structure, each Cd II cation is in a distorted octahedral coordination environment, coordinated by the N and S atoms of nicotinic acid and thiocyanate ligands. Neighbouring Cd II cations are linked together by thiocyanate bridges to form a two‐dimensional network. Hydrogen‐bond interactions between the uncoordinated solvent water molecules and the organic ligands result in the formation of the three‐dimensional supramolecular network.
