Novel heterobimetallic thiocarboxylato complexes: synthesis, characterization and application as single source precursor for ternary chalcogenides

Abstract

Heterobimetallic complexes, (PPh₃)₂M(μ-SCOPh)₂Pb(SCOPh) [where, M = Cu^I (1) or Ag^I (2)] have been synthesized and characterized by FTIR, ¹H, ¹³C and ³¹P NMR spectroscopy. Molecular structures in solid state have been determined by single crystal X-ray diffraction. Electronic spectra of the compounds have been recorded and explained on the basis of TDDFT calculations. Luminescence and redox properties of the complexes have also been studied. Following the thermogravimetric analysis data the compounds were pyrolysed and one of the decomposition products has been characterized as Pb₄Cu₅O_22.6 (3) by SEM-EDX and X-ray diffraction studies.
