title: [Cis-[eta(2)-(Ph(3)PAu)(2)]Ph(3)PCr(CO)(4)].THF, featuring the shortest known separation between two Au metal centres in a heteronuclear Au(2)M cluster.
abstract: The title compound, tetracarbonyl-1kappa(4)C-tris(triphenylphosphino)-1kappaP,2kappaP,3kappaP-triangulo-chromiumdigold(Au-Au)(2 Cr-Au) tetrahydrofuran solvate, [Au(2)Cr(C(18)H(15)P)(3)(CO)(4)].C(4)H(8)O, is a stable isolobal analogue of the extremely labile [(eta(2)-H(2))CrL(n-1)] molecular hydrogen complex (n = 6; L is a neutral ligand, e.g. CO or PPh(3)), and features the shortest known separation [2.6937 (2) A] between two Au atoms in a triangular heteronuclear metal-cluster framework.
