Reactions of LH=RCSNHCOOEt (R= 4-tolyl, 1-pyrrolyl, and 2- thiophenyl) with RuCl₃. 3H₂O and NO leads to the formation of diamagnetic compounds of the formula [L₂Ru(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 bound cis to NO by N-hetrocycles bases (a-picoline, y-picoline and or pyridine) and CH₃CN has significant effect on the electronic properties of complexes.
