摘要：

The new oxometallates (I) Ba5Mn4Sm8O21 and (II) Ba5Mn4Ho8O21 were prepared by CO2 laser high temperature reactions under reducing conditions and investigated by X-ray single-crystal methods. These compounds crystallize with tetragonal symmetry, space group C4h5-I4/m; (I) a = 14.0911 angstrom; c = 5.8329 angstrom; (II) a = 13.8507 angstrom, c = 5.7452 angstrom; Z = 2. There exists a remarkable relationship with oxides of the formula BaMLn2O5. The similarities and differences with respect to the polyhedra around Ln3+ and the two point positions of Ba2+ are discussed.
