| Abstract | ||
| A new series of transition metal complexes of Cu(II) , Co(II) , Ni(II) , Cd(II) , Zn(II) and VO(IV) were synthesized from the Schiff base (L) derived from isonicotinic acid hydrazide and o-vanilline . Structural features were obtained from their metal analysis ,magnetic susceptibility , molar conductance , IR and UV-Vis spectral studies . the data showed that these complexes have the composition of ML3 type for Cu(II) , Co(II) , Ni(II) while ML2 type for Zn(II), Cd(II) and VO(IV) .According to the the UV-Vis , magnetic susceptibility data of the complexes an octahedral geometry was suggested for Cu(II) , Co(II) & Ni(II) metal ions and a tetrahedral geometry for Cd(II) & Zn(II) metal ions, while a squarepyramidal geometry was suggested for VO(IV) ion . | ||
