溶液中絡合物的研究大多偏重于由相同配位体組成的单一型絡合物,单核的或多核的。但是在生产或者在分析过程中,往往是同时存在着不同的配位体,阴离子或中性分子,因此对于一些复杂的溶液体系仅仅考虑单核的或多核的单一型絡合物的平衡是不够的,有时还有可能引出不正确的結論。因为在一定的条件下,体系中除了单核的或多核的单一型絡合物平衡以外,还可能存在着混合型絡合物的平衡。所謂混合型絡合物就是由二种或二种以上的不同的配位体所組成的絡合物,可以是单核的,也可能是莎核的混合型絡合物。对于混合型絡合物在很早以前就有許多学者进行了研究,但主要是偏重于制备及其物理和化学性貭的
Most studies of complexes in solution have focused on single-type complexes consisting of the same ligands, mononuclear or polynuclear. However, during production or during the analysis, different ligands, anions or neutral molecules often exist at the same time. Therefore, it is not enough to consider the balance of mononuclear or polynuclear mono-type complexes for some complex solution systems And sometimes it can lead to incorrect conclusions. Because under certain conditions, in addition to the system of mononuclear or polynuclear single complex balance, there may be mixed complex balance. The so-called mixed complex is composed of two or more different ligand complex, which may be mononuclear, may also be hybrid corerickham complex. Many scholars have studied the mixed complex a long time ago, but mainly focused on the preparation and its physical and chemical properties
