The asymmetric unit of the title complex contains one half of the complex molecule, one and a half ZnII cations, three benzoate (Bnz) and one pyridine-3-carbonitrile (CPy) molecule; the Bnz anions act as bidentate ligands through the carboxylate O atoms, while the Cpy anion acts as a monodentate N(pyridine)-bonding ligand. The complete centrosymmetric trinuclear complex thus comprises a linear array of three ZnII cations. In the crystal, the Bnz anions link to the Cpy N atoms via weak C—H⋯N hydrogen bonds, forming a two-dimensional network. The Hirshfeld surface analysis confirms the role of H-atom contacts in establishing the packing.
