Poly[[μ4-4-(carboxylatomethyl)benzoato]zinc(II)]

Abstract

In the title compound, [Zn(C9H6O4)]n, the ZnII cations are coordinated in a tetrahedral fashion by carboxylate O-atom donors belonging to four 4-(carboxymethyl) benzoate (4-cmb) ligands. Each 4-cmb ligand binds to four ZnII cations in an exotetradentate fashion to create a non-interpenetrated [Zn(4-cmb)]n three-dimensional coordination polymer network with a new non-diamondoid 66 topology. The crystal studied was refined as an inversion twin.
