N2  - 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 P&#299; with a 14.310(1), b 11.080(2), c 16.099(3) &#506;, &#945; 68.30(2), &#946; 90.78(2), &#947; 75.04(1)°. The structure analysis has been based on 2964 independent reflection intensities (Cu K&#945; 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) &#506;, &#946; 101.59(2)°. Refinement by least squares has converged to R 0.093 for the 2256 independent reflection intensities, observed by Mo K&#945; automatic diffractometry. The preferred stereochemistries of the five-coordinate cobalt complexes are discussed in relation to the bite angle of the chelating phosphine.
