Complexes of Platinum, Rhodium, Iridium and Ruthenium with a Thiosemicarbazone Derived from Thiophene-3-carboxaldehyde

摘要

Complexes of thiophene-3-carboxaldehyde thiosemicarbazone with Ru3+, Rh3+, Ir3+and Pt4+have been prepared and characterized by elemental analyses, molar conductance, magnetic moments, infrared and electronic spectral studies. Probable structures for the complexes are suggested. All are diamagnetic except the Ru3+complexes and possess octathedral structures. The crystal field parameters of the complexes have also been calculated.
