title: trans-Bis[1,2-bis(diphenylphosphino)ethane-kappa(2)P,P']bis[4-(trimethylsilyl)buta-1,3-diynyl]ruthenium(II) and trans-bis[1,2-bis(diphenylphosphino)ethane-kappa(2)P,P']bis(buta-1,3-diynyl)ruthenium(II).
abstract: The crystal structures of the title compounds, [Ru(C(7)H(9)Si)(2)(C(26)H(24)P(2))(2)] and [Ru(C(4)H)(2)(C(26)H(24)P(2))(2)], are described. The metal centre in both complexes has an octahedral coordination geometry, with mutually trans buta-1,3-diynyl ligands forming pseudo-linear ruthenium-centred polyyne chains.
