Various ?-alkylvanadium complexes of the general formula RV(CO)npm (n = 4, 3; pm is an m-dentate phosphine coordinating through (6 - n) P-functions) have been prepared by photo-reaction between the hydrido precursors HV(CO)npm and alkenes, and characterized by IR- and 51V NMR spectroscopy.The preparation of the new phosphines Me2P(CH2)3P(ⁱPr)2 and ⁱPrP(CH2CH2CH2PMe2)2 is described. trans- crystallizes in the space group P<*>1 with the following cell parameters: a = 1012.1(9), b = 1012.9(6), c = 1224.7(9) pm, a = 105.780(6), β = 102.601(7)deg.
