Ruthenium complexes containing Group 5B donor ligands. Part 5. Synthesis and crystal and molecular structure of acetone(carbonyl)-chloro(trichlorostannio)bis(triphenylphosphine)ruthenium(II)–acetone(1/1)

Abstract

The lemon-yellow crystals (1) obtained by reaction of the red ‘carbonyl-containing’ ruthenium solution with SnCl₂ and PPh₃ in acetone have been shown to be [RuCl(SnCl₃)(CO)(PPh₃)₂(OCMe₂)]·Me₂CO and not [Ru₂Cl₃(SnCl₃)(CO)₂(PPh₃)₂(OCMe₂)₂](3) as previously suggested. The crystals are monoclinic, space group P2₁/c with a= 11.950(3), b= 14.988(3), c= 24.916(2)Å, and β= 92.51(1)°. The structure has been solved with 3 601 diffractometer data and refined to R 0.037. It is, however, possible to obtain (3) by warming (1) in benzene, but it readily loses SnCl₂ to give some [(Ph₃P)(OC)ClRuCl₃Ru(CO)(PPh₃)₂].
