Replacement of MeCN in Ru(C{double bond}CPhC(CF{sub 3}){sub 2}C(CN){sub 2})(NCMe)(PPh{sub 3})({eta}-C{sub 5}H{sub 5}), readily obtained from the bis-PPh{sub 3} complex in MeCN, by a series of organonitrile ligands (CH{sub 2}{double bond}CHCN,trans-CH(CH){double bond}CH(CN), C(CN){sub 2}{double bond}C(CF{sub 3}){sub 2} (dcfe), C{sub 2}(CN){sub 4}, o-C{sub 6}H{sub 4}(CN){sub 2}, p-C{sub 6}H{sub 4}(CN){sub 2}, o-C{sub 6}F{sub 4}(CN){sub 2}, p-C{sub 6}F{sub 4}(CN){sub 2}, C{sub 6}H{sub 2}(CN){sub 4}) has given highly colored complexes containing one or two Ru(C{double bond}CPhC(CF{sub 3}){sub 2}C(CN){sub 2})(PPh{sub 3})({eta}-C{sub 5}H{sub 5}) moieties. The binuclear complexes are bridged by the di- or tetranitriles; isomers were found for the fumaronitrile, dcfe, and C{sub 2}(CN){sub 4} derivaties. The deep blue {mu}-dcfe complexes are readily oxidized to green paramagnetic species that appear to contain an epoxy radical ligand. The complexes were characterized by spectroscopic and electrochemical studies and, in the case of the title complexes, by single-crystal X-ray diffraction studies. The structures were refined by a full-matrix (blocked-matrix for 2a) least-squares procedure to final R = 0.059 and R{sub w} = 0.064 for 3,883 reflections with I {ge} 2.5{sigma}(I) for 4 and R = 0.045 and R{sub w} = 0.045 for 1,708 reflections for 2a.
