Synthesis, spectroscopic, structural characterization of Cd(II) and Zn(II) complexes based on the N-methyl-C-(2-pyridyl)nitrone

摘要

Zinc and cadmium complexes, ML2(NO3)(2) (L = N-methyl-C-(2-pyridyl)nitrone) were synthesized and characterized by means of X-ray diffraction crystallography and IR and NMR spectroscopy. The organic ligands in the complexes are coordinated via the oxygen atom of the nitrone group and the nitrogen atom of the pyridine moiety. The coordination environment of the central atoms is a distorted octahedron. The bond lengths and angles of the complexes were calculated using the DFT method with B3LYP functional. Theoretical studies revealed that the geometric parameters are in agreement with the experimental data. The fluorescent properties for the zinc and cadmium complexes were investigated at room temperature.
