摘要：

Small single crystals having the composition LaMo7.70O14 were prepared by fused salt electrolysis of a mixture of Na2MoO4, MoO3, and La2O3. The compound is orthorhombic with a = 11.1708(6), b = 9.98489(9), and c = 9.1960(7) Å. The structure was solved by X-ray diffraction methods in space group C2ca with R = 0.030 and RW = 0.040 for 1878 reflections. The dominant feature of the structure is a novel Mo8 cluster formed by capping two faces of an Mo6 octahedron which share an edge in common. In spite of its uniqueness, the structure can be described elegantly in terms of a hexagonal closest packing of oxygens. © 1990.
