The reactions of the ligand bis[(2-diphenylphosphino)ethyl]ether (POP) with the nitrido precursors Mv NCl2(PPh3)2 and [Mvi NCl4]- (M= Tc, Re) and mixed ligand complexes with mercaptoacetic acid (HL1) , S-methyldithiocarbazate (HL2) and N_acetyl-L-cysteine (HL3) chelators have been investigated. The use of the POP hetero-diphosphine allows the preparation of asymmetrical nitrido species and, at carrier free level, the procedure offers an easy new opportunity to label biologically active molecule.
