Abstract

A new tris-chelate Cd(II) complex, [Cd(DADMBTZ)3](ClO3)2 has been successfully synthesized and characterized by IR, 1H, 13C NMR spectroscopy, elemental analysis and single crystal X-ray determination. The thermal behavior, UV-Vis and fluorescence spectra of compound were studied. In reaction with DADMBTZ, Cadmium (II) forms a tris-chelate complex with nearly C3 symmetry for coordination polyhedron, DADMBTZ acts as a bidentate ligand. In complex the ClO3 – anions are symmetrically different. Complex makes 2-D and 3-D networks via N-H…O and N-H…N hydrogen bonds, respectively. The nanocomposite CdO-CdS have been prepared using [Cd(DADMBTZ)3](ClO3)2 as precursor via thermal decomposition. As-prepared CdO-CdS nanocomposite was characterized By X-ray diffraction measurements (XRD), scanning electron microscopy (SEM).
