The synthesis of vinylidene, trans-[(dppm)2ClMCC(H)(R)]PF6, and σ-acetylide complexes, trans-[(dppm)2ClMCCR] (M = Ru, Os; dppm = bis(diphenylphosphino)methane, Ph2PCH2PPh2; R = p-C6H5, p-C6H4C6H5, p-C6H42, C6H32-(CH3)-4-NO2, p-C6H4CH3), and a single-crystal X-ray determination of trans-[(dppm)2ClRuCCC6H4-p-NO2] are reported. The metal-phosphine fragment in these complexes acts as a donor and communicates with the para-substituted nitro acceptor group through the backbone. Such an interaction helps create a delocalized charge-transfer state from the donor to the acceptor.
