Ruthenium(II) carbonyl complexes with thiosemicarbazone ligands

This paper presents a combined experimental and computational study of Ru(II) carbonyl complexes containing thiosemicarbazone ligands. Five novel [Ru(H/Cl)(L)(PPh3)2] complexes have been obtained and characterized by IR, 1H, 13C, 31P NMR, UV–Vis spectroscopy and X-ray crystallography. Their electronic structures have been determined using the density functional theory (DFT) method and employed for a discussion of their properties. The donor–acceptor properties of the ligands were correlated with the substituent positions on the benzene ring. The luminescence properties of the complexes have also been examined.
