GermaniumI 4700 Synthesis and Characterization of a Cadmium Germanium Phosphate

CdGe(OH)3PO4 with an Open Framework. — The new title compound is solvo-thermally synthesized from GeO2, H3PO4, and Cd(NO3)2 in the presence of NEt3 (H2O/1,2-propanediol (5.3:1), autoclave, 120 °C, 8 d, 85% yield). CdGe(OH)3PO4 crystallizes in the orthorhombic space group Cmca with Z = 8 (single crystal XRD). Its open-framework structure consists of a mixed network of GeO6 octahedra, CdO6 octa-hedra, and PO4 tetrahedra and contains one-dimensional channels formed by 3- and 6-membered rings. The synthesis of CdGe(OH)3PO4 may lead to other metal germani-um phosphates with novel structures and properties such as adsorption, catalysis, ionic conduction, low thermal expansion, and magnetic properties. — (LIU, Y.; YANG, X.-L.; WANG, G.-L.; ZHANG, J.; LI, Y.-Z.; DU*, H.-B.; YOU, X.-Z.; J.
