Abstract

The reactions of cis-[Ru(CO)₂X₂]_n, (X = CI, Br or I) with ligands (I.H),N,N-dimethyl-N′-phenylthiourea (dmptH) and 1,3-thiazolidine-2-thione (tzdtH), yield [Ru(CO)₂X₂(LH)₂]. These complexes have been characterized by analytical, conductivity, IR, electronic (UV-Vis), ¹H and ¹³C NMR, and FAB mass spectroscopic studies. Low-frequency IR spectra (FTIR) reveal that the ligands (LH) bind through the thione sulphur atom to ruthenium. In all cases a distorted octahedral environment of a cis, cis, cis-structure is suggested.
