Synthesis and Physiochemical studies of some metal complexes of Ti(III) with Phthalimide or Succinimide

Mixed ligand complexes of Ti(III) with phthalimide or succinimide as primary ligands and amino acids as secondary ligands have been synthesized. The general formula of these complexes are follows: K[Ti(L)2 (L′)2 ] where L= phthalimide; C8H4O2N(1-3), succinimide; C4H4O2N(4-6); and L′ =amino acids. The complexes were prepared in the solid form and characterization by elemental analysis, conductivity, magnetic moment measurement, IR, 1H-NMR, 13C-NMR, FAB+ mass and electronic spectroscopic studies. The value of 10 Dq was found to be 12250-13965 cm-1 for all complexes. The value of B, β and ligand field stabilization energy have also been calculated from the bands obtained in the electronic spectra of the complexes . Electronic and other measurements confirmed their octahedral structure.
