Abstract:

A new schiff base contaning cyclohexyl moiety and phenyl group i.e. p-hydroxy benzyliden phenyl imine (CSSB), have been prepared, and was reacted with a number of transition metal ions, which include: (V+4 , Cr+3 , Fe+2 , Co+2 , Ni+2 , Cu+2 , Zn+2 , Cd+2 , Hg+2 and Pd+2) CSSB was characterized by it's FT-IR spectrum, while it's complexes were characterized by their electronic (uv-vis) spectra and vibrational (FT-IR) spectra, metal analysis (using atomic absorption technique), conductivity and magnetic susciptibility measurments. The new colored complexes show to have the following general formula 1-[M L2 (X) (M)].S X=M=zero S=Zero when M= Vo(II) X=Cl,M=H2O S= Zero when M= Cr(III) X=M=H2O S=2H2O when M=Fe(II) NO3 ,M=H2O S=Zero when M= Co(II) X=M=H2O S=Zero when M=Ni(II) X=M=H2O S=Zero when M=Cu(II) X=M=Zero S=2Cl when M= Zn(II) X=M=Zero S=2Cl.C2H5OH when M= Cd(II) X=M=Zero S= 2Cl.C2H5OH when M= Hg(II) X=M=Zero S=2Cl when M= Pd(II) The vibrational and elucidation electronic spectral studies and conductivity measurment were very useful in the illusidation of the structural formula of the prepared complexes, which were either octahedral (Vo+2 , Cr+3 , Cu+2 , Co+2 , Ni+2 , Fe+2), square planar (for Pd+2) or tetrahedral (for Zn+2 , Cd+2 , Hg+2).
