A re-examination of the reaction of dichloro-tris-(triphenylphosphino)ruthenium(II) with benzonitrile: Crystal structures of triphenylphosphine chloro ruthenium complexes

The reaction of RuCl2(PPh3)3 with excess benzonitrile yields cis-RuCl2(PPh3)2(NCPh)2, whereas (PPh3)2(Cl)Ru(μ-Cl)3Ru(NCPh)(PPh3)2 is obtained with excess RuCl2(PPh3)3.71
