摘要：

[P(C6H5)4]2[As10Se3], [P(Ph)4]2[As10Se3], M(r) = 1664.5, triclinic, P1BAR, a = 9.291 (3), b = 10.554 (5), c = 27.038 (6) angstrom, alpha = 90.10 (3), beta = 95.64 (2), lambda = 91.33 (4)degrees, V = 2637 (4) angstrom 3, Z = 2, D(x) = 2.095 Mg m-3, Mo K-alpha, lambda = 0.71069 angstrom, mu = 8.1 mm-1, T = 293 K, F(000) = 1580, final R = 0.057, wR = 0.059 for 3337 observed reflections. The compound contains the polycyclic anion As10Se3(2-) which displays an orientational disorder over two symmetrical arrangements (with 85.4% and 14.6% occupancy) around the 1/4, 1/2, 3/4 position.
