摘要：

cis-[UO2Cl2(tppo)2], [UCl2O2(C18H15OP)2], (1), M(r) = 897.52, monoclinic, C2/c, a = 17.233 (3), b = 12.112 (2), c = 17.085 (4) angstrom, beta = 105.90 (2)degrees, V = 3429.7 angstrom 3, Z = 4, D(x) = 1.737 g cm-3, Mo K-alpha, lambda = 0.71073 angstrom, mu = 47.64 cm-1, F(000) = 1736, T = 293 K, R = 0.040 for 2855 observed reflections with I > 3-sigma(I). trans-[UO2Cl2(tppo)2], [UCl2O2(C18H15OP)2], (2), M(r) = 897.52, monoclinic, B2(1), a = 10.158 (11), b = 18.849 (17), c = 19.139 (14) angstrom, beta = 90.4 (1)degrees, V = 3664.4 angstrom 3, Z = 4, D(x) = 1.638 g cm-3, Mo K-alpha, lambda = 0.71073 angstrom, mu = 44.74 cm-1, F(000) = 1736, T = 293 K, R = 0.042 for 2603 observed reflections with I > 3-sigma(I). In both forms the complex has a distorted octahedral arrangement about the U atom.
