The Coordination of 4,7-Diphenyl-1,10-Phenanthroline with d10 Configuration Metal Ions Zn2+, Cd2+ and Hg2+

Abstract

Abstract: The coordination mechanism of 4,7-diphenyl-1, 10-phenanthroline with d10 configuration metal ions Zn²⁺ , Cd²⁺ and Hg²⁺ has been discussed with the aid of NMRtechnigue 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.
