摘要：

La4MO2O11, M(r) = 923.51, tetragonal, P4(2)/n, a = 12.989 (1), c = 5.6523 (7) angstrom, v = 953.6 (I)angstrom3, Z = 4, D(x) = 6.4 32 g cm-3, lambda(Mo Kalpha) = 0.71073 angstrom , mu = 201.5 cm , F(000) = 1600, T = 295 K, R = 0.018 for 1478 observed reflections. La4Mo2O11 is isostructural with Nd4Re2O11 and contains isolated Mo2O10 units. The Mo-Mo distance is 2.5905 (5) angstrom and the Mo-O distances are in the range 1.847 (2)-2.207 (2) angstrom. The units are interconnected with LaO8 pseudo cubes and bicapped trigonal prisms in which the ranges of the La-O distances are 2.3853 (2)-2.637 (2) angstrom and 2.368 (2)-2.903 (2) angstrom respectively.
