title: Bis{mu-(E)-2-[(2-pyridylamino)(2-pyridylimino)methyl]benzato}bis[acetatozinc(II)] tetrahydrate.
abstract: In the C(2)-symmetric dinuclear title complex, [Zn(2)(C(18)H(13)N(4)O(2))(2)(C(2)H(3)O(2))(2)] x 4 H(2)O, each Zn(II) ion is five-coordinated in a distorted trigonal bipyramidal fashion by one carboxylate O atom from one benzoate ligand, one imine N atom and two pyridyl N atoms from a second benzoate ligand, and one O atom from an acetate anion. The two Zn atoms are bridged by the two benzoate ligands, forming a dinuclear structure with a 14-membered macrocycle. Adjacent dinuclear units are further connected by extensive hydrogen bonds involving the solvent water molecules, giving a three-dimensional hydrogen-bonded framework. The framework can be regarded as an example of the four-connected node network of the PtS topology.
