The Coordination of 4,7-Diphenyl-1,10-Phenanthroline with d~10 Configuration Metal Ions Zn^(2+) , Cd^(2+) and Hg^(2+)

用NMR与光度分析联用的方法对4,7-二苯基-1,10-二氮杂菲与d10组态金属Zn^(2+)、Cd^(2+)、Hg^(2+)的配位机理进行了探讨,确定了配合物组成并对配合物结构及其中弯曲配键进行了推断,提出了一种从实验直接研究无d-d跃迁的以d10离子为中心的配合物配位过程以及难分离配合物配位构型测定的方法。

The coordination mechanism of 4,7-diphenyl-1, 10-phenanthroline with d10 configuration metal ions Zn^(2+) , Cd^(2+) and Hg^(2+) has been discussed with the aid of NMR technigue and spectrophotometry. The compositions of the complexes were determined, and the circumstance of coordinatioh equilibriums in the complex process was analysed. The scale of stability of coordination bonde has been set up. So we have inferred the structures of the complexes and the bent coordination bond in them. The problem on studying directly coordination mechanism of complexes with central ions of d10 configuration without d-d transition was solved and the stereo-configuration of the complexes separated difficultly was determined experimentally.
