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′-X2-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
各种溶剂对的一般类型的复合物的可见光区域的电子吸收光谱的影响[M(CO)4(Ñ,Ñ '-X 2 -bipy)](M =铬,钼,W; Ñ = 3 ; 4、5、6; X = CH 3,CN,CO 2 CH 3;联吡啶= 2,2′-联吡啶)。报告了摩尔吸收系数。尝试使此信息与Manuta和Lees提出的溶剂极性参数相关联,表明在基质复合物中几何变形的影响无法通过单一参数对观察结果进行简单的解释。
