Poly[diaqua-μ₂-oxalato-di-μ₄-succinato-diyttrium(III)]

Abstract

In the title compound, [Y2(C4H4O4)2(C2O4)(H2O)2]n, the flexible succinate anion assumes a gauche conformation and bridges the eight-coordinated Y atoms, generating two-dimensional layers parallel to (010). The coordination polymer layers are linked into a three-dimensional framework by the rigid oxalate ligands. The oxalate ions are located on a center of inversion. Inter­molecular O—H⋯O hydrogen bonds help to stabilize the crystal structure.
