A two-dimensional coordination polymer containing a two-dimensional zinc–carboxylate layer constructed from helical chains: poly[(μ4-benzene-1,2-dicarboxylato)zinc(II)

Abstract

The title compound, [Zn(C(8)H(4)O(4))](n), consists of one Zn(II) cation and one benzene-1,2-dicarboxylate dianion (BDC(2-)) as the building unit. The Zn(II) cation is four-coordinated by four carboxylate O atoms from four dianionic BDC(2-) ligands in a distorted tetrahedral geometry. The Zn(II) cations are linked by the BDC(2-) ligands to generate a structure featuring two-dimensional zinc-carboxylate layers containing left- and right-handed helical chains. The two-dimensional layers are stacked along the a direction. The thermal stability of the title compound has been studied.
