Ein Beitrag zur Kristallstruktur von CuSmMo2O8 und CuGdMo2O8

A Contribution on the Crystal Structure of CuSmMo₂O₈ and CuGdMo₂O₈ Single crystals of (I) CuSmMo₂O₈ and (II) CuGdMo₂O₈ were prepared and investigated using an X-ray technique. Both compounds crystallize with orthorhombic symmetry, space group D-Pbca with Z = 8. ((I): a = 10.302, b = 9.796, c = 14.697 Å; (II): a = 10.200, b = 9.779, c = 14.646 Å). The crystal structure and the classification into the already known Copper(I) Lanthanoidemolybdates are discussed.
