Poly[diaqua(μ(2)-oxalato-κO,O:O,O)(μ(2)-pyrazine-2-carboxyl-ato-κN,O:O')cerium(III)].

ABSTRACT: In the hydro-thermally synthesized title compound, [Ce(C(5)H(3)N(2)O(2))(C(2)O(4))(H(2)O)(2)](n), the Ce(III) ion is coordinated by four O atoms from two different oxalate ligands, three O atoms from two symmetry-related pyrazine-2-carboxyl-ate ligands, two O atoms from two water melecules and one N atom from a pyrazine-2-carboxyl-ate ligand in a distorted bicapped square-anti-prismatic coordination geometry. The oxalate and pyrazine-2-carboxyl-ate ligands bridge the Ce(III) ions, forming a two-dimensional structure. In addition, inter-molecular O-H⋯O and O-H⋯N hydrogen bonds connect the two-dimensional structure into a three-dimensional network.
