Bis{μ‐(E)‐2‐[(2‐pyridylamino)(2‐pyridylimino)methyl]benzato}bis[acetatozinc(II)] tetrahydrate

In the C₂‐symmetric dinuclear title complex, Zn₂(C₁₈H₁₃N₄O₂)₂(C₂H₃O₂)₂]·4H₂O, 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.
