摘要：

({eta(5)-3-[2-(Di-tert-butylphosphino)ethyl]-cyclopentadienyl}(dimethyl)(eta(5)-tetramethylcyclopentadienyl)silane)bis(trimethylsilyl)methylscandium, C33H62PScSi3, M(r) = 595.04, monoclinic, P2(1)/n, a = 14.449 (3), b = 12.807 (5), c = 20.848 (5) angstrom, beta = 99.52 (2)-degrees, V = 3804.8 (18) angstrom 3, Z = 4, D(x) = 1.04 g cm-3, lambda(Mo K-alpha) = 0.71073 angstrom, mu = 3.18 cm-1, F(000) = 1352, T = 296 K, final R = 0.108 for 3100 reflections with F0(2) > 0, 0.054 for 1766 reflections with F0(2) > 3-sigma(F0(2)). The Sc-C(1) bond [2.253 (8) angstrom] is insignificantly shorter than the 2.271 (7) angstrom found in a similar compound; the geometry about C(1) is nearly trigonal, with angles 118.5 (5), 116.0 (5) and 119.4 (6)-degrees.
