Abstract:Transition metal complexes of ditertiary aminomethylphosphine ligand, (Ph2PCH2)NCH3 N,N‐bis(diphenylphospinomethyl)aminomethane], dppam, with metal ions which are Ag(I), Au(I), Cu(I), and Co(II) have been synthesized under nitrogen atmosphere by the Schlenk method. Ag(dppam)2]NO3 ( 1 ), Au(dppam)2]Cl ( 2 ), and Cu(dppam)2]Cl ( 3 ) complexes have been isolated as colorless solids, whereas CoCl2(dppam)] ( 4 ) complex as a blue solid. All complexes have been characterized by atomic absorption, FT‐IR, NMR (1H, 13C, 31P) spectroscopic, thermogravimetric/differantial thermal analysis (TG/DTA), and elemental analysis techniques. Antimicrobial activity of 1 , 2 , 3 , and 4 were studied in vitro on 13 bacteria and 4 yeasts. The cobalt(II) phosphine complex has shown the best antimicrobial activity in comparison with the other metal complexes. © 2005 Wiley Periodicals, Inc.
