Synthesis and characterize Schiff Base compound

A new Schiff Base ligand [(SBDTC)2AP] has been synthesized by the 1:2 condensation of Acetophenone and S-benzyldithiocarbazate. A group of selected ions such as Cu(II), Cd(II), Zn(II), Ni(II) and Co(II) complexes of [(SBDTC)2AP] have been prepared and characterized by elemental analysis, spectroscopic studies and various physico-chemical techniques included melting point determination, IR spectra and Uv-Vis spectra. Melting point of Schiff base is basically lower than metal complexes because of intra-molecular interaction. The FTIR spectrum for Schiff base ligand shows stretching vibration of the important functional group ;v(N-H) in range ~3179 cm-1,v(C=S) in range ~1103cm-1,v(N-N-C) in range ~1344cm-1,v(C=N) in range ~ 1599 cm-1 and lastly v(C-S-S) in range of 1027 cm-1.As for the metal complexes of Schiff base, they posses in thiol form in solid state because of the v(N-H) and v(C=S) stretching disappearance near 3179 cm-1 and 1103 cm-1 respectively. The coordination of the azomethine nitrogen and sulfur donors atom to the metal is indicate by the shift on the v(C=N) band at 1599 cm-1 and in the v(C-S-S) band at 921 cm-1 .
