A mathematical correlation of the MLCT absorption maxima of structurally related fac‐[M(CO)3L2Br] complexes (M = Mn, Re; L2 = bidentate ligand) is obtained by the comparison of a total of 50 species bearing bipyridine, pyridinylpyrazine, azopyridine and pyridin‐2‐ylmethanimine L2 type ligands. The empirical relationship is first derived by the initial comparison of the MLCT absorption maxima of 26

配体。经验关系首先通过对先前发布的26种复合物的MLCT吸收最大值进行初步比较得出,然后用于预测其他24种物种的相同吸收值。为了检查预测的有效性,准备了几种新的配合物。对它们进行了光谱表征,并在可能的情况下阐明了其X射线固态结构。初始的数学相关性可以预测未知物种的MLCT吸收最大值,平均差异为12 nm。随后利用以下导出的公式Calc Mn m LCT =(Obs Re MLCT /0.88)– 15.1将关系精炼为平均误差为6 nm。计算Mn m LCT = Mn配合物MLCT和Obs Re的预测值MLCT =实验观察到的Re配合物的MLCT转变。从长远来看,相关性和
