摘要：

The influence of various solvents on the electronic absorption spectra in the visible region of complexes of the general type [M(CO)(4)(n,n'-X(2)-bipy)] (M = Cr, Mo, W; n = 3, 4, 5, 6; X = CH3, CN, CO2CH3; bipy = 2,2'-bipyridine) has been measured. Molar absorption coefficients are reported. Attempts to correlate this information with the solvent polarity parameter proposed by Manuta and Lees indicate that the effects of geometric distortion in the substrate complex preclude a simple explanation of the observations in terms of a single parameter.
