The novel structure of the [Au11(PMePh2)10]3+ cation: Crystal structures of [Au11(PMePh2)10][C2B 9H12]3·4thf and [Au11(PMePh2)10][C2B 9H12]3 (thf = tetrahydrofuran)

Crystal structure analyses of [Au11(PMePh2)10][C2B 9H12]3·4thf (thf = tetrahydrofuran) and [Au11(PMePh2)10][C2B 9H12]3 showed the metal framework of the [Au11(PMePh2)10]3+ cation to approximate to a centred bicapped square antiprism, with idealized D4d symmetry. Symmetry-related cage distances and angles have similar mean values but different ranges in the two structures, with the latter having greater consistency in the peripheral bond lengths but more distortion in the squares of the antiprism. It is suggested that these differences are directly related to the ligand packing around the metal skeletons. The cations of the two clusters cannot be superimposed in any orientation. It is possible to relate a centred bicapped square antiprism to the previously reported undecagold cage geometry, although they belong to different symmetry point groups. The largest differences between the idealized C3v and D4d frameworks centre around three adjacent peripheral sites. The movements required to interconvert the geometries take place about a common mirror plane and appear to be closely related to those of the diamond-square-diamond rearrangement mechanism. Fluxional interconversions of this type provide a possible explanation for the 31P-{1H} NMR spectra of the Au11 cluster compounds.

Transition-Metal Silyl Complexes, 26. - Gold(I) Silyl Complexes

Complexes of type L-Au-SiR3 with L = PR'3 or PhNC and SiR3 = Si(aryl)3, Si(SiMe3)3, or SiPh2Me are prepared by reaction of L-Au-Cl with LiSiR3.Depending on L and R, their stability decreases in the order R'3P-Au-Si(aryl)3 > R'3P-Au-Si(SiMe3)3 > R'3P-Au-SiPh2Me ca.PhNC-Au-SiR3.Reaction of R'3P-Au-CH3 or R'3P-Au-OAc with HSiR3 does not yield silyl complexes.However, using chlorinated silanes like HSiR2Cl, CH3/Cl or OAc/Cl exchange takes place.The Moessbauer spectrum of MePh2P-Au-SiPh3 (6) and NMR- and IR-spectroscopic investigations show that silyl groups act as strong ? donors towards the gold atom.MePh2P-Au-SiPh3 (6) and MePh2P-Au-Si(SiMe3)3 (7) have been characterized by X-ray structure analyses .The Au-Si bond in MePh2P-Au-SiPh2Tol (5) is cleaved by X2 (X = Cl, Br, I), HCl or MeI, but not by H2O or MeOH. - Keywords: Gold(I) silyl complexes / Transition-metal silyl complexes
