Palladium(II) and platinum(II) complexes of 2,9-Dimethyl-1,10-phenanthroline. I. Halide compounds

Abstract

Complexes of 2,9-dimethyl-1,10-phenanthroline with palladium(II) and platinum(II) halides are described. The methyl groups of the ligand introduce strong steric hindrance in some of the normal geometries of these transition-metal complexes, and evidence is presented for five- coordination in the bis(dmp) compounds of these two metals.
