title: Poly[diaqua-μ(2)-oxalato-di-μ(4)-succinato-diyttrium(III)].
abstract: In the title compound, [Y(2)(C(4)H(4)O(4))(2)(C(2)O(4))(H(2)O)(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. Inter-molecular O-H⋯O hydrogen bonds help to stabilize the crystal structure.
