Structure of bis[cis-1,2-bis(diphenylphosphino)ethylene] dichlororhenium(II) hexane solvate

[ReCl2(C26H22P2)2].C6H14 (I), M(r) = 1136.11, monoclinic, P2(1)/c, a = 11.426 (2), b = 13.078 (2), c = 17.323 (3) A, beta = 95.27 (1) degrees, V = 2577.7 (6) A3, Z = 2, Dx = 1.46 g cm-3, lambda(Mo K alpha) = 0.71073 A, mu = 26.5 cm-1, F(000) = 1150, T = 296 K, R = 0.034 for 3269 [Fo2 > 3 sigma(Fo2)] reflections. The Re atom in (I) is located on an inversion point, fixed at the origin. One Cl and a complete tertiary phosphine ligand (Ph2PCHCHPPh2) are situated around the Re atom so as to generate a pseudo-octahedral geometry with a P1--Re--P2 angle of 79.07 (5) degrees and P1--Re--P2' angle of 100.93 (5) degrees. The Re--Cl, Re--P1 and Re--P2 distances are 2.432 (2), 2.401 (2) and 2.398 (2) A, respectively. Bond distances and angles for the phenyl rings range from 1.34 (1) to 1.41 (1) A and 117.4 (6) to 122.0 (7) degrees with averages of 1.38 (1) A and 120.0 (1) degrees, respectively.
