Abstract
The reaction of [PdCl2(dppf)] with the sodium salt of pyridyl/pyrimidyl tellurolate resulted a mononuclear cis configured complex [Pd(TeAr)2(dppf)] (Ar = C5H4N, C4H3N2). These complexes were characterized by NMR (1H, 31P) spectroscopy and elemental analysis. In addition, the thin film of this complex was fabricated on the glass using solution process and it was found to be sensitive towards detection of H2S gas. The chemi-resistive response of the film was ascribed to the fact that an auxiliary tellurolate ligand attached to palladium metal centre substituted reversibly by thiolate (HS−) species of hydrogen sulphide gas.
