The molecular structures of eight nitrile complexes of general form [M(NCC 6H 4R-4)(L 2)Cp′]PF 6 [M = Fe, Ru; L 2 = dppe, (PPh 3) 2; Cp′ = Cp, Cp*] are reported and discussed in terms of the nature of the M–N interaction. Data are consistent with a predominantly σ-interaction, similar to that found in related acetylide complexes, with little evidence for metal to nitrile π-back bonding interactions.
