Stable salts of the η5-cyclohexadienylphosphoniumruthenium(II) complexes [(η5-C6H6PR3)RuL3]2+ (PR3 PMe3, PMe2Ph; L3 (PMe3)3, (PMe3)2PPh3, (PMe3)(PPh3)PMe2Ph, (PMe3)2P(NMe2)3, (PMe3)2MeCN) are obtained from [C6H6RuClL2]PF6, C6H6RuCl2(L) or [C6H6Ru(MeCN)3](PF6)2 and excess phosphine. At low temperature, both the 1H and 31P NMR spectra indicate a restricted rotation around the metal-to-ring bond.
