Abstract

In the title compound, [KLu(C2O4)2(H2O)4]n, the LuIII ion lies on a site of 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.

Republic of China

R factor = 0.014; wR factor = 0.035; data-to-parameter ratio = 16.0. In the title compound, [KLu(C2O4)2(H2O)4]n, the Lu ion lies on a site of 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. The mid-point of the C—C bond of the oxalate group lies on an inversion center. Each oxalate ligand links two Lu(III) and two K atoms, forming a three-dimensional open framework with channels running along [001]. Symmetry codes: (i) x þ 1; y þ 12; z; (ii) y þ 14; x þ 14; z þ 14.
