The title compound, [Zn4(C7H4O3)4(C10H8N2)4]·10H2O, crystallizes as a centrosymmetric tetranuclear cyclic complex containing four ZnII atoms bridged by four carboxylate groups from salicylate ligands, with a syn–anti configuration. Each ZnII atom has a distorted trigonal–bipyramidal coordination geometry, formed by two N atoms of a 2,2′-bipyridine ligand and three O atoms from two salicylate ligands. The complex is stabilized by intramolecular – interactions between pairs of bipyridine rings and a 16-membered gear-wheel-shaped cyclic framework. The hydrogen-bonding network is formed via the water molecules.
