The synthetic utility of bis(trimethylstannyl)alkynyls in the preparation of Group 8 metal (Fe2+, Ru2+, Os2+) σ-acetylide monomeric, M(DEPE)2(CCC6H5)2 (M Fe2+, Ru2+; DEPE = 1,2-bis(diethylphosphino)ethane), Ru(DPPE)2 (CCC6H5)2 (DPPE = 1,2-bis(diphenylphosphino)ethane), Os(DPPM)2(CCC6H5) 2 (DPPM = 1,2-bis(diphenylphosphino)methane) and polymeric, [M(DEPE)2CCRCC]n (M Fe2+, Ru2+), [Os(DPPM)2CCRCC-]n (R = p-C6H4- C6H4-p, p-C6H4, p-C6H2(CH3)2) complexes is demonstrated. The linear arrangement of the acetylenic units around octahedral metal centres is confirmed by a single crystal X-ray structure determination of the model complex trans-[Ru(DPPE) 2(CCC6H5)2].
