Abstract

Monosubstituted [M (N) Cl2 (POP)][M= Tc, 1; Re, 2] and [M (N) Cl2 (PNP)][M= Tc, 3; Re, 4] complexes were prepared by reaction of the precursors [M (N) Cl4]-and [M (N) Cl2 (PPh3) 2](M= Tc, Re) with the diphosphine ligands bis (2-diphenylphosphinoethyl) ether (POP) and bis (2-diphenylphosphinoethyl) methoxyethylamine (PNP) in refluxing dichloromethane/ methanol solutions. In these compounds, the diphosphine acted as a chelating ligand ...
