Abstract
Pd(ll) and Ni(ll) complexes of bis(diphenylphosphinemethyl) aminobutyl, ((Ph2PCH2)2N(CH2)3(CH3)3), were synthesized using Schlenck techniques under nitrogen atmosphere. Synthesized complexes were characterized by using thermal analysis, elemental analyses, 1H NMR, 31P NMR, FT-IR and UV–Vis techniques. Single crystal X-Ray diffraction analysis confirms the structure of the newly synthesized compounds. The electrochemical properties of complexes were studied by using cyclic voltammetry. All complexes exhibited intra-ligand (π→π*) fluorescence in CH2Cl2. Hartree Fock was used to determine the electronic structure and properties of the complexes. Band gaps of the newly synthesized complexes were calculated as 3.19eV and 3.15eV and showed good optical properties.
