Zinc(II) and nickel(II) complexes with N-[2-(2-diethylphoshponylethyliminomethyl) phenyl]-4-methylbenzenesulfonamide: Synthesis, structure, and photoluminescence properties

Two Zn(II) and Ni(II) complexes derived from the N-[2-(2-diethylphosphonylethyliminomethyl)phenyl]-4methylbenzenesulfonamide ligand (HL) with stoichiometry ML2 (M = Zn, Ni) have been synthesized. Their structures have been established using elemental analysis, IR, 1H NMR, UV-Vis spectroscopy, and synchrotron single-crystal X-ray diffraction. The Zn(II) and Ni(II) metal sites therein adopt the tetrahedral configuration. The DMSO and toluene solutions of the Zn(II) complex manifest photoluminescence in the blue-violet spectral range characterized by PL maxima at 436 and 432 nm and quantum yields of 0.15 and 0.30, respectively.
