and conformer populations for a variety of cylic and acyclic (diene)Fe(CO)2L complexes (L = phosphine, phosphite, isonitrile). The solid state structures of (2,3-dimethylbutadiene)Fe(CO)2PPh3 and (trans,trans-2,4-hexadiene)Fe(CO)2PPh3 have been determined and used as a basis for molecular modelling of steric effects in these complexes.
可变温度13 C和31 P NMR光谱已用于建立各种环状和非环状(二烯)Fe(CO)2 L配合物(L =膦,亚磷酸酯,异腈)的溶液结构和构象体种群。(2,3-二甲基丁二烯)Fe(CO)2 PPh 3和(反式,反式-2,4-己二烯)Fe(CO)2 PPh 3的固态结构已经确定,并用作分子模型的基础这些配合物中的空间位阻效应。
