Inorganic and Analytical


Salicylaldehyde ethoxythiocarbonyl hydrazone (H2L) forms adducts as well as deprotonated complexes having 1:1 or/and 1:2 metal ligand ratio with the metal ions VO(IV), Ni(II), Co(III), Cu(II), Zn(II), Mn(II) and Fe(II). Based on magnetic,esr, electronic, infrared andnmr spectral measurements, structures have been assigned to all the compounds,ir spectral studies show neutral bidentate behaviour of the ligand in the adducts and uninegative/binegative tridentate behaviour in the deprotonated complexes, the bonding sites being azomethine nitrogen and thione sulphur in the former type of complexes and phenolate oxygen, azomethine nitrogen and thione/thiolate sulphur in the latter type.
