Abstract

X-ray diffraction analysis of the two complexes [CoPhP{(CH2)3PPh2}2P(OMe)3CO] BF4, thf and [CoPhP{(CH2)2PPh2}2{P(OMe)3}2] BF4 are reported. Crystals of the first complex are triclinic, space group Pī with a 14.310(1), b 11.080(2), c 16.099(3) Å, α 68.30(2), β 90.78(2), γ 75.04(1)°. The structure analysis has been based on 2964 independent reflection intensities (Cu Kα automatic diffractometry) to give R 0.11. The second complex is monoclinic, space group P21/c, with a 13.18(4), b 11.49(3), c 29.66(6) Å, β 101.59(2)°. Refinement by least squares has converged to R 0.093 for the 2256 independent reflection intensities, observed by Mo Kα automatic diffractometry. The preferred stereochemistries..
