Poly[tetraaquadi-μ4-oxalato-lutetium(III)potassium]

Abstract

In the title compound, [KLu(C2O4)2(H2O)4]n, the LuIII ion lies on a site of overline{4} symmetry in a dodecahedron defined by eight O atoms from four oxalate ligands. The K atom lies on another site of the same symmetry and is coordinated by four oxalate O atoms and four O water atoms. The mid-point of the C—C bond of the oxalate group lies on an inversion center. In the packing structure, each oxalate ligand links two Lu(III) and two K atoms, forming a three-dimensional open framework with channels running along [001]. Intermolecular O—H...O hydrogen bonds occur.
