Abstract (1-Benzyl-2-imidazolyl)diphenylphosphine [(BzIm)Ph 2 P] can act as a monodentate or bidentate ligand to afford mononuclear (BzIm)Ph 2 PAuCl ( I ) or dinuclear [μ-(BzIm)Ph 2 PAu] 2 2+ 2X − (X = PF 6 − , BF 4 − or NO 3 − ) ( IIa,b,c ) derivatives of gold(I). Analogous dinuclear silver(I) derivatives were obtained reacting the ligand [(BzIm)Ph 2 P] with AgX salts (X = NO 3 − , BF 4 − ) ( IIIa,b ). In solution the silver complexes show a fluxional behaviour, and two conformers were… Expand
