✦ Synopsis

Transition metal complexes of diter- tiary aminomethylphosphine ligand, (Ph 2 PCH 2 )NCH 3 [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 ]NO 3 (1), [Au(dppam) 2 ]Cl (2), and [Cu(dppam) 2 ]Cl (3) complexes have been isolated as colorless solids, whereas [CoCl 2 (dppam)] (4) complex as a blue solid. All complexes have been characterized by atomic absorption, FT-IR, NMR ( 1 H, 13 C, 31 P) 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.
