Abstract
This presentation intends to discuss the design and synthesis of low temperature single source molecular precursors for the synthesis of palladium chalcogenides, both in bulk and nano-size regime. Thus a variety of organochalcogenolates of palladium and platinum differing in nuclearity (mono-, bi-, tri- and hexa- nuclear) have been isolated and characterized by uv-vis, NMR ( 1 H, 13 C, 31 P, 77 Se, 125 Te, 195 Pt) spectroscopy and X-ray crystallography. Thermal behavior of several complexes, such as [Pd(SeCOAr) 2 (PR 3 ) 2 ], [Pd(OAc)(ECH 2 CH 2 CH 2 NMe 2 )] 2 , etc. has been studied by TG analyses. Solvothermal decomposition yields palladium chalcogenides nano-particles (e.g., Pd 7 Te 3 , Pd 17 Se 15 ) which were characterized by XRD, EDAX and SEM method.
