The Heteronuclear Cluster Chemistry of the Group 1 B Metals. Part 11. Effect of the Nature of the Bidentate Diphosphine Ligand on the Metal Framework Structures of the Gold Heteronuclear Cluster Compounds (n = 1-6). X-Ray Crystal Stru…
Treatment of acetone solutions of the salt 2 with a dichloromethane solution of the appropriate complex (n = 1-6), in the presence of TlPF6, affords the mixed-metal cluster compounds in ca. 60-70percent yield.X-Ray diffraction studies on (2) and (3) reveal that the formal replacement of the two PPh3 ligands attached to the Au atoms in (1) by Ph2P(CH2)nPPh2 (n = 1 or 2) alters the capped trigonal-bipyramidal skeletal geometry adopted by (1).The cluster (2) crystallizes in two forms, monoclinic and orthorhombic, but X-ray diffraction studies on both forms show that the molecular structures adopted by (2) are closely similar in each case.The metal core of (2) consists of a square-based pyramid, defined by two Au atoms in the basal plane and a Ru atom at the apex, with the Ru3 face of this Au2Ru3 unit capped by a Ru atom .The Ph2PCH2PPh2 ligand bridges the two Au atoms, one hydrido ligand caps a Ru3 face and one bridges a Ru-Ru edge of the metal framework, and each Ru atoms is ligated by three terminal CO groups.The skeletal geometry of (3) is reasonably similar to that exhibited by (1), but one of the Au-Ru distances <3.446(4) Angstroem> is too long for any significant bonding interaction between the two atoms.Thus, the metal framework of (3) is somewhat distorted towards a capped square-based pyramid .Variable-temperature 1H and 31P-(1H) n.m.r. studies show that, at ambient temperature in solution, the metal cores of (3)-(7) all undergo dynamic behaviour involving gold atom site exchange.
