Zur Kristallstruktur von CuInMo2O8

On the Crystal Structure of CuInMo₂O₈ . Single crystals of CuInMo₂O₈ were prepared and investigated by X-ray work. It shows monoclinic symmetry, space group C—C2/c; a = 9.549 Å, b = 11.529 Å, c = 5.000 Å; β = 91.38(2)°, Z = 4. CuInMo₂O₈ represents a LiYbW₂O₈ related structure, characterised by zigzag-chains of MoO₆-octahedrons and octahedrons around copper and indium. With respect to LiFeW₂O₈ the single and three-valent ions are in opposite distribution. There are strong evidence for molybdenum in lowered oxidation state.
