MP2 calculations show that the D isoelectronic dicarbonyl complexes [M(CO) ] (M =Rh , Pd , Cu , Ag , Au , Zn , Cd , Hg ) depicted in structure 1 can be classified as classical or nonclassical depending on whether the metal-carbon bond lengths decrease or increase when weak, anionic ligands approach the metal centers.
MP2计算表明，结构1中所示的等电子双羰基配合物[M(CO)₂]（M = Rh、Pd、Cu、Ag、Au、Zn、Cd、Hg）可根据弱阴离子配体接近金属中心时金属-碳键长度是减小还是增加，分为经典或非经典类型。
