Synthesis, Characterization and Reaction of New Ruthenium Aromatic Thioamide Nitrosyls with some Nitrogen Donor Ligands

Abstract

Reactions of LH=RCSNHCOOEt (R= 4-tolyl, 1-pyrrolyl, and 2-thiophenyl) with RuCl 3 . 3H 2 O and NO leads to the formation of diamagnetic compounds of the formula [L 2 Ru(NO)(Cl)J]. These compounds have been characterised by elemental analysis and IR, UV and Visible and magnetic measurements. The presence of (NO) at 1835-1855-cm -1 indicates a {Ru-NO} 6 configuration. The substitution of Cl bounded trans to NO by N-hetrocycles bases (a-picoline, y-picoline and or pyridine) and CH 3 CN has significant effect on the electronic properties of complexes.
