Rb3Mo14O22 has been prepared and its crystal structure determined: S.G.: P21/c (No.14), a = 10.462(7), b = 9.414(2), c = 9.956(5) Ǻ, β = 103.73(2)°, Z = 2, R = 0.046. It is isotypic to K3Mo14O22. The crystal structure can be described as a substitutional derivative of a ccp close packing of oxygen and rubidium atoms with interspersed Mo14O34 units having a core of three trans-edge condensed molybdenum octahedra. The observed multiple twinning is explained by this structural model. A bond valence analysis is presented. |
