Neutral R3PAuGe9(Hyp)3 (R=Et, nPr, iPr, nBu, tBu, Cy) (Hyp=Si(SiMe3) Clusters give new insights into the ligand strength of the metalloid [Ge9(Hyp)3]? cluster

We present new insights into the ligand strength of the metalloid [Ge9(Hyp)3]? cluster (Hyp=Si(SiMe3)3) alongside novel neutral Ge9 clusters of the composition R3PAuGe9(Hyp)3 (R=Et, nPr, iPr, nBu, tBu, Cy). These clusters are synthesized in good yields from KGe9(Hyp)3 and R3PAuCl. Further experiments with these new clusters show that the ligand strength of [Ge9(Hyp)3]? is in between aryl and alkyl phosphines.

Diphenylphosphide-bridged diiron derivatives of [Fe 2(η5-C5H5)2(μ-H) (μ-PPh2)(CO)2]

The complex trans-[Fe2Cp2(μ-H)(μ-PPh 2)(CO)2] is obtained in 91% yield by refluxing toluene solutions of [Fe2Cp2(CO)4] (Cp = μ5-C5H5) and the secondary phosphine PPh2H. This compound isomerizes upon irradiation with visible - UV light under a CO atmosphere to yield cis-[Fe2Cp2(μ-H) (μ-PPh2)(CO)2]. The above hydride complexes react under photochemical conditions with 1 equiv of secondary phosphines PR2H (R = Et, Ph) to give the corresponding monocarbonyl compounds [Fe 2Cp2(μ-PPh2)(μ-PR2)(μ-CO)] via the hydride intermediates [Fe2Cp2(μ-H)(μ- PPh2)(CO)(PR2H)] (detected and isolated for R = Et). Deprotonation of trans[Fe2Cp2(μ-H)(μ-PPh 2)(CO)2] with LiBu gives the binuclear anion [Fe 2Cp2(μ-PPh2)(CO)2]. This highly nucleophilic carbonylate reacts rapidly with [AuCl(PiPr3)] or MeI to give the corresponding gold diiron cluster [AuFe2Cp 2(μ-PPh2)(CO)2(PiPr3)] or methyl derivative [Fe2Cp2(Me)(μ-PPh 2)(μ-CO)(CO)2], respectively. Both hydrides cis- and trans- [Fe2Cp2(μ-H)(μPPh2)(CO) 2] can be reversibly oxidized at low temperature to the corresponding cation radicals cis- and trans- [Fe2Cp2(μ-H)(H- PPh2)(CO)2]-. At room temperature, however, the trans dicarbonyl cation isomerizes to its cis isomer, which in turn experiences a degradation process involving the reductive elimination of the bridging groups. The structures of the new complexes are analyzed on the basis of the corresponding IR and NMR (1H, 31P and 13C) spectroscopic data. The nature of the new radical cations is analyzed also on the basis of cyclic voltammetry and ESR measurements.

Preparation and Structure of Hexakismethanium(2+) Salts (2+)(X(1-))2 with L = Et3P, iPr3P and X = BF4(1-), B3O3F4(1-)

Hexaaurated carbon complexes of the type (BF4)2, R = Et (2a), iPr (2b) have been prepared by the reaction of the appropriate (phosphane)gold(I) chlorides R3PAuCl (1a and 1b) with tetrakis(dimethoxyboryl)methane, (13)C-enriched at the central carbon atom, in the presence of excess of CsF in HMPT at room temperature.The products 2a and 2b are characterized by standard spectroscopic methods including direct detection of the interstitial C atoms by (13)C-NMR spectroscopy.The crystal structure of the compound (B3O3F4)2*3CH2Cl2 (3), obtained from partial (anion) hydrolysis has been determined.It contains dications with a central carbon atom surrounded by six (phosphane)gold(I) units.The edges of the CAu6 octahedron represent short Au-Au contacts (aprox. 3.0 Angstroem), which strongly contribute to the formation and stability of these hypercoordinated species.Attempts to prepare a corresponding hexaauriomethanium dication starting from tBu3PAuCl (1c) failed owing to the bulkiness of the (tri-tert-butylphosphane)gold(I) unit.The X-ray structure analysis for 1c verifies an extremly crowded environment of the gold atom with small Au-P-C-angles of only 107 deg leading to efficient shielding of the metal atom by methyl groups.
