Abstract Single crystals of (I) CuDyMo2O8 and (II) CuYbMo2O8 have been prepared by crystalli­sation from melts. Both com pounds crystallize with orthorhombic symmetry, space group D152h-Pbca with (I): a = 10.195(1), b = 9.721(2), c = 14.563(3); (II): a = 10.094(6), b = 9.628(9), c = 14.467(8) Å, Z = 8. The crystal structure is characterized by a triangular CuO3-polygon, a square antiprismatic coordination around the Rare Earth ions and the typical Mo O4 tetra­ hedra.

Abstract Single Crystals of Pb2LnAl3O8 (Ln = Eu, Gd) have been prepared by flux techniques. The compounds crystallize with cubic symmetry, space group Oh-Pn3̅m, a(Eu) = 9.4578(5), a(Gd) = 9.4448(7) Å, Z = 4. The crystal structure is characterized by heterocubane units of the type Pb4O4 and hexagonal bipyramids of oxygen around the rare earth ions. These components form a network made of macro polyhedra of the type Pb4O4- LnO6- Pb4O4
