({η^5-3-[2-(Di-tert-butylphosphino)ethyl]-cyclopentadienyl} (dimethyl)(η^5-tetramethylcyclopentadienyl)silane)bis(trimethylsilyl)methylscandium, C_(33)H_(62)PScSi_3, M_r = 595.04, monoclinic, P2_1/n, ɑ = 14.449 (3), b = 12.807 (5), c = 20.848 (5) Å, β = 99.52 (2)º, V = 3804.8 (18) Å^3, Z = 4, D_x = 1.04 g cm^(-3), λ(Mo Kɑ)= 0.71073 Å,μ = 3.18 cm^(-1)F(000) = 1352, T = 296 K, final R = 0.108 for 3100 reflections with F_o^2 > 0, 0.054 for 1766 reflections with F_o^2 > 3σ(F_o^2). The Sc-C(l) bond [2.253 (8) Å] is insignificantly shorter than the 2.271 (7) Å found in a similar compound; the geometry about C(l) is nearly trigonal, with angles 118.5 (5), 116.0 (5) and 119.4(6)º.
