Abstract: The title compound, [Zn(C8H4O4)]n, consists of one ZnII cation and one benzene-1,2-dicarboxylate dianion (BDC2-) as the building unit. The ZnII cation is four-coordinated by four carboxylate O atoms from four dianionic BDC2- ligands in a distorted tetrahedral geometry. The ZnII cations are linked by the BDC2- 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.
