The new Schiff base derived from 3-Phenyl-propenal and 2,2-Dimethylpropane- 1,3-diamineand its cadmium(II) complexes have been synthesized and characterized by various physical and spectral techniques such as elemental analysis, molar conductance measurements, FT-IR, 1H and 13C NMR and UVÂVisible spectroscopy. The spectral studies confirm that the ligand act as bidentate molecule and coordinatesmetal through azomethine nitrogen. The elemental analysis data exhibit the molar ratio between ligand and cadmiumsalts is 1:1 and lowmolar conductivities of complexes are the reason for stabilization of molecular structure and non-electrolyte nature of these complexes. The changes in the location and shape of the peaks in UVvisible, FT-IR, and the 1H and 13C NMR spectra of complexes rather than free ligand are the other evidence to formSchiff base complexes. In respect to resulting data, the CdLX2 (X= Cl-,Br-and I-) as general formula and pseudotetrahedral structure has been suggested for these complexes.
