Abstract:
Two new substituted-thioimidophonate derivatives H1L1 (O,O',O'',O'''-diaryldithioimidophonates) and H1L2 (O,O',O'',O'''-tetra aryldithioimidophonates) were synthesized. These thioimidophonates are potential ligands towards transition metal ions. The reaction of M(II) acetates (M(II)=Mn(II), Co(II), Ni(II), Cu(II), and Zn(II)) with H1L1 and H1L2 resulted in the formation of solid complexes with the composition (L1/L2)(2)M(II). These compounds were characterized through elemental analysis, electrical conductance, infrared, electronic spectra, nmr, magnetic susceptibilities etc. Vibrational mode assignments of nu(PN), nu(PS), nu(MS), phenyl and methyl group bands are made. Structural and bonding changes are correlated with these vibrational frequencies. All the compounds were screened for their antibacterial and antifungal properties and have exhibited potential activities with MIC (0.09-1.50 microg/ml).
