Herein are described some continuing investigations into the reactions of cyano‐alkenes with diynyl‐ruthenium complexes which have resulted in the preparation and characterisation of diynyl‐ruthenium compounds Ru(C≡CC≡C R )(PP)Cp [ R = Ph, PP = dppe; R = Fc, PP = dppf; R = CPh=CBr 2 , PP = (PPh 3 ) 2 ], together with the polycyanobutadienyls Ru{C≡CC[=C(CN) 2 ]C R =C R ′(CN)}(PP)Cp′ [ R = Fc, (PP)Cp′ = (dppf)Cp; R = H, SiMe 3 , (PP)Cp′ = (dppe)Cp*] formed by [2 + 2]‐cycloaddition of the cyano‐alkenes to the outer C≡C triple bonds and subsequent ring‐opening reactions. Single‐crystal XRD molecular structure determinations of six complexes are reported.
