Abstract

The Cd atom in the title complex, [Cd(C2H3O2)(NCS)(C7H8N4O)(H2O)]·H2O, is coordinated by one neutral Schiff base ligand, one acetate anion, one thiocyanate anion and one water molecule, forming a distorted pentagonal–bipyramidal geometry. The thiocyanate S atom and the coordinated water ligand occupy the apical positions of the coordination polyhedron. The acetate acts as a bidentate ligand through the carboxylate O atoms. The Schiff base, derived from the condensation of pyridine‐2‐carbaldehyde and semicarbazone, acts as a tridentate ligand, coordinating the metal through the amide, imine and pyridyl N atoms in a meridional fashion. The crystal packing is stabilized by π–π stacking interactions between the neighboring pyridine rings and hydrogen bonds involving the Schiff base, thiocyanate, water molecules and uncoordinated solvent water molecules.
