Abstract

The neutral cluster [Ir6(CO)15(AuPPh3)21 has been obtained by reaction of [IrdC0)15I2- with [AuPPh3]+. The iridium atoms of the cluster define an octahedral frame capped by one gold-phosphine group. The second AuPPh3 unit spans one Ir-Au edge. The metal skeleton of C1 symmetry is coordinated by twelve terminal and three edge-bridging carbonyl groups. The dianionic [IrdcO)14(Hgc1)21~- has been prepared from [Irs(C0)15l2- and Hg2C12, HgC12 + Hg, or HgClz in the presence of Na2C03. The metallic framework forms an octahedron of iridium atoms bearing, on four non-adjacent faces, two ,u3-HgC1 fragments and two ,u3-C0 groups. The chemical shift of the lg9Hg NMR was found at +1508 ppm.
