 Abstract    (V0)(P04)2 und BaC d(V 0)(P04)2: Zum BaZn(V0)(P04)2-Typ verwandte, jedoch nicht isotype Vanadylphosphate SrZ n(V 0)(P 04)2 and B a C d (V 0)(P 04)2: Vanadylphosphates Related but not Isotypic to the B aZ n (V 0)(P 04)2 Type Single crystals of the compounds S rZ n (V 0)(P 0 4)2 (I) and B aC d(V 0)(P04)2 (II) ha­ ve been prepared by solid state reactions in evacuated quartz tubes. X-ray investigati­ ons confirmed orthorhombic symmetry, space group D ^-P bca, lattice constants a/b/c (I): 9.066(1)/9 .0 1 2 (l)/l7.513(1) A and (II); 8.838(4)/8.915(4)/19.374(9) Ä, Z = 8. Initially assu­ med isotypies of (I) and (II) to B aZ n(V 0)(P 04)2 proved to be erroneous considering significant details of the connectivity of the Z n 0 4 and P 0 4 tetrahedra (I) and the coordination sphere of cadmium (II), respectively. The similarities and differences of the crystal chemistry relation to (I) and (II) are discussed with respect to B a Z n(V 0)(P 04)2. The Coulomb terms of the lattice energies of vanadyl M2(V 0)(P 0 4)2 and divanadyl M (V 0)2(P 0 4)2 phosphates are shown.

 Title    Uber ein cadmiumreiches Orthovanadat Ba2,5Cd11(V 04)9 mit Cadmium in oktaedrischer und tetragonal pyramidaler Koordination On a Cadmium Rich Orthovanadate Ba-, 3Cd, |( V 0 4)9 Showing Cadmium in Octahedral and Square Pyramidal Coordination  
 Abstract    Single crystals of Ba2 ^C di^V O ^g have been prepared by solid state reactions. The new compound crystallizes with orthorhombic symmetry, space group D ^-Pbcn, a = 20.842(6), b = 13.471(3), c = 11.838(9) A, Z = 4. The crystal structure is characterized and dominated by C d 0 6 octahedra and unusual square pyramids of 0 2~ around Cd2+ forming a three-dimensional [C d ]|0 36] network. The interstices are occupied by V 5+ and Ba2+ ions. This results in V 0 4 tetrahedra and irregular BaO 10 polyhedra isolated from each other. Occupation of the barium positions is deficient in agreement with the valence state V5+ and calculations of the coulomb terms of lattice energy.
