Complexes of Fe(II), Co (II) Ag (I) and Hg (II) have been synthesized with the drug Dapsone that is 4-4’diaminodiphenyl sulfone. Conductometric studies and elemental analysis suggest the ML2 stoichiometry for Fe(II), Co (II) Hg (II) complexes and ML1 for Ag (I) complex. Molar conductance values indicate the non-electrolytic nature of the complexes. The ligand behaves as bidentate ligand and forms co-ordinate bond through azomethine nitrogen(-C=N-).The structure assigned to the complexes, synthesized via Schiff base formation is supported by infrared spectral studies.
