Ligand substitution at five-co-ordinate centres: associate mechanism for the high-spin complex 2,9-dimethyl-1,10-phenanthrolinebis-(OO′-dimethyl dithiophosphato)nickel(II)

Abstract

The reaction between bis(OO′-dimethyl dithiophosphato)nickel(II) and 2,9-dimethyl-1,10-phenanthroline giving a high-spin five-co-ordinate adduct has been investigated; the adduct reacts with 2,2′-bipyridyl and 1,10-phenanthroline by an almost exclusively associative mechanism.
