Preparation and spectroscopic investigation of new mixed ligand chelates

الملخص EN

Novel mixed ligand chelates of Ti (IV), Cr (IU) and Fe (III) ions with salicylaldehyde and dithiol have been prepared and investigated by different techniques, in particular, elemental analysis(CHS), molar conductance measurements, infrared and electronic spectra.

The elemental analysis data exhibit the formation of M : L : L'[1 : 1 : 1] ratio.

The molar conductance measurements indicate the presence of non-electrolytic nature of the prepared complexes.

The infrared spectra reveal one mode for complexation site, through sulfur atoms of the dithiol and oxygen atoms of the carbonyl (C = 0) and the hydroxyl groups of salicylaldehyde.

The electronic absorption spectra show the existence of an octahedral geometry.
