摘要

C18F15P, Mr = 532.1, monoclinic, P2(1)/c, a = 7.194 (2), b = 17.930 (4), c = 13.834 (2) A, beta = 94.29 (2) degrees, V = 1779 A3, Z = 4, Dm = 2.00, Dx = 1.99 g cm-3, lambda(Mo K alpha) = 0.71073 A, mu = 3.3 cm-1, F(000) = 1032, T approximately equal to 296 K, final R = 0.055 for 2352 unique observed reflections. The three planar C6F5 groups are twisted about the C-P bonds to give extensive deviations from molecular C3 symmetry similar to those in the crystal structure of triphenylphosphine. The P-C bond lengths and C-P-C bond angles are 1.834 (4), 1.832 (4), 1.824 (4) A and 104.4 (2), 106.0 (2), 99.6 (1) degree, respectively. There are two short C...F non-bonded distances in the structure (2.99, 2.79 A).
