摘要：

The structure of hexagonal dicobalt dipotassium triselenite, K2Co2(SeO3)3, is composed of CoO6 octahedra, KO9 polyhedra and two crystallographically different types of pyramidal SeO3 groups. Pairs of face-sharing CoO6 octahedra are linked via the SeO3 groups forming [Co2(SeO3)3]2 layers parallel to (0001), which are connected by the K atoms. This new structure type is closely related to the buetschliite-type compounds K2M(XO3)2 (M = Ca, Mg with X = C, and M = Co, Mn with X = Se).
