Synthesis and structural studies of the ruthenium(II) 'sandwich' compl
exes [Ru(eta(5)-P(3)C(2)(t)Bu(2))(2)], ta(5)-P(3)C(2)(t)Bu(2))(eta(5)-
P(2)C(3)(t)Bu(3))], and [Ru(eta(5)-C(5)R(5))(eta(5)-P(3)C(2)(t)Bu(2))]
(R = H, Me) are described. The results of a single crystal X-ray stru
ctural study of [Ru(eta 5-P(3)C(2)(t)Bu(2))(2)] are discussed.
