络合物的分子轨函数理论上期讲的晶体场理论是根据这样的假设建立的,金属离子和它周围的配位体(负离子或偶极离子)的相互作用是纯粹的静电作用,意谓金属离子轨函数和配位体轨函数并不混合(即重叠),因而完全没有共价键的性质。实验证明金属离子轨函数和配位体确实有些重叠,即晶体场理论能够很成功地用上的络合物也是如此。这些实验类型是:电子自旋共振、核磁共振,金属离子 d 轨函数的吸收光谱、络合物的磁化率等。因 The theory of molecular orbital functions of complexes is based on the assumption that the interaction of metal ions with its surrounding ligands (negative ions or dipole ions) is a purely electrostatic interaction, meaning that the metal The ion orbit function and the orbitor function are not mixed (ie, overlapped) and thus have no covalent bond properties at all. Experiments have shown that the metal ion orbital function does indeed overlap with the ligands, as is the case with complexes that the crystal field theory can successfully use. These experimental types are: electron spin resonance, nuclear magnetic resonance, absorption spectra of metal ion d-orbital functions, magnetic susceptibility of complexes, and the like. because
