Reactions of RCSNHCOR'(R and R¢ are various types of group) with Cis - [RuCl₂ (DMSO)₄ ] in presence of nitric oxide and pyridine leads to the formation of new  complexes of the type cis-[RuCl₂(NO)(RCSNHCOR')(py)]⁺. These cationic complexes were isolated as cis [RuCl₂(NO) (RCSNHCOR') (py)] PF₆ on reacting with NH₄PF₆. The complexes were characterised by elemental analysis, spectroscopic (Infrared, UV-Vis), conductometric and magnetic studies. An intence band at 1840-1850 cm^–1 appeared in all the complexes, suggesting a {Ru-NO}⁶ type configuration of all these ruthenium nitrosyls presence of chloride ligand trans to NO and pyridine in plane have considerable change in properties of complexes.
