摘要：

The title compound, [Er(C8H4NO2)(3)(H2O)(2)](n), has a one-dimensional chain structure bridged by carboxylate groups. The Er-III atom and one 3-cyanobenzoate ligand lie on a twofold axis and this ligand has its cyano group disordered over two sites. Each Er-III atom is surrounded by two O atoms from one chelating carboxylate group, four O atoms from four different bridging carboxylate groups and two water molecules, leading to a square-antiprism coordination polyhedron.
