synthesis, spectral and theoretical studies of some new complexes of mercury with a new asymmetric bidentate schiff base ligand

synthesis, identification and theoretical studies of a new asymmetric bidentate schiff base 2-(4-chloro- (benzylideneimine) thiophenol (l) and its complexes with general formula hgl(ph), hgl2 and hglx₂ (x= clˉ, brˉ, iˉ) were described. authenticity of the ligand and its complexes has been established by microanalyses, ft-ir, uv-vis, ¹h nmr, ¹³c nmr spectra and by molar conductivity measurements, the complexes are non-electrolytes in dmf. the electronic spectra of the complexes were recorded in dmf solution. ¹h and ¹³c nmr spectra been studied in cdcl₃. the hglx₂, phhgl and hgl₂ complexes have suggested to be pseudo-tetrahedral geometry.
