Abstract
C28H28P2, Mr = 426.48, monoclinic, P21/c, a = 6.134
(2), b = 8.166 (3), c = 24.636 (5) A, β =106.4 (2)º, V = 1184 A3, Z = 2, Dm = 1.120, Dx = 1.196 g cm-3, λ(Mo Kα) = 0.71069 A, μ = 1.55
cm-1, F(000) = 452, T = 295 K, R = 0.051 for 924 unique reflections with I > 3σ (I). The structure found for the free ligand is very similar to that reported for the one coordinated to Rh atoms in
[Rh2 {Ph2 P(CH2)4 PPh2} - (η-C5H5)2 (CO)2], the only known X-ray determination of this ligand. The
-(CH2)4- moiety is planar within 0.004 (5) A with the P atoms + 0.105 (2) and -0.105 (2) A from its calculated mean plane. The P atoms have the usual distorted tetrahedral configuration.
