M. Peruzzini et al., Reaction of [(PPh3)(3)RuCl2] with white phosphorus: synthesis of the firstRu-II complex featuring a tetrahedro-tetraphosphorus ligand, MENDELEEV C, (4), 2000, pp. 134-135
The title reaction affords slightly air- and light-sensitive [(PPh3)(2)ClRu
(mu-Cl)(3)Ru(PPh3)(2)(eta(1)-P-4)], which belongs to a very rare family of
soluble tetrahedro-tetraphosphorus complexes and represents the first ruthe
nium species of this type.
