We report a joint experimental and theoretical study on the structures of a series of gold clusters doped with a sulfur atom, Au(x)S(-) (x = 2-5). Well-resolved photoelectron spectra are obtained and compared with theoretical results calculated using several density functional methods to elucidate the structures and bonding of Au(x)S(-) (x = 2-5). Au2S(-) is found to have an asymmetric linear g...

Iranian Cenozoic magmatic belt, known as Urumieh-Dokhtar, is recognized as an important polymetallic mineralization which hosts porphyry, epithermal, and polymetallic skarn deposits. In this regard, multivariate analyses are generally used to extract significant anomalous geochemical signature of the mineral deposits. In this study, stepwise factor analysis, cluster analysis, and concentration–...

Automotive is requesting engine control IC to operate in 145°C ambient. Power Gold technology can allow ICs to operate hotter. Since more power dissipates from molded package and across FR4 board with ICs at 175°C Tj-max instead of at present 125°C or 150°C, Power Au technology enhances power product. Continuous, reliable 175°C Tjmax operation is achieved with Power Au. Top silicon metallizatio...

The title compound, [Au(C(8)H(7)ClNOS)(C(18)H(15)P)], is characterized by a linear S,P-donor set with a small deviation from the ideal linearity [S-Au-P = 175.14 (5)°] due to the close approach of the O atom to the Au atom [Au⋯O = 2.882 (3) Å]. Loosely associated dimers are formed in the crystal structure through C-H⋯O inter-actions.

The Au atom in the title compound, [Au(C(8)H(7)ClNOS)(C(18)H(15)P)], exists within a slightly distorted linear geometry defined by an S,P-donor set [S-Au-P angle = 174.61 (4)°], with the distortion related to a short intra-molecular Au⋯O contact [2.988 (3) Å]. In the crystal structure, mol-ecules are arranged into supra-molecular chains along the b axis by C-H⋯π inter-actions.

The title compound, [Au(C(9)H(9)ClNOS)(C(18)H(15)P)], reveals a near linear geometry for the Au atom defined by a S,P-donor set [S-Au-P = 175.86 (3)°]. The deviation from linearity is ascribed to the proximate O atom derived from the thio-carbamato anion [Au⋯O = 2.967 (3) Å].

The Au atom in the title compound, [Au(C(10)H(11)ClNOS)(C(18)H(33)P)], is coordinated within an S,P-donor set that defines a slightly distorted linear geometry [S-Au-P = 172.45 (5)°], with the distortion due in part to a close intra-molecular Au⋯O contact [3.134 (3) Å].

The PHENIX Experiment at the Relativistic Heavy Ion Collider has performed a survey of momentum correlations ranging from 200 MeV/c to 7 GeV/c in √ sNN = 200 GeV p+p, d+Au, Au+Au, and √ sNN = 62 GeV Au+Au collisions. The correlations are measured separately for like-sign and unlike-sign pairs. Comparisons of the properties of the near-side peak amplitude and width as a function of centrality an...

A nearly linear coordination geometry for Au is found in the title compound, [Au(C(9)H(9)N(2)O(3)S)(C(21)H(21)P)]. The thio-carbamate ligand is orientated so that the aryl group is in close proximity to the Au atom, consistent with an Au⋯π contact [Au⋯Cg = 3.351 (5) Å; Cg is the centroid of the aromatic ring].

The Au(I) atom in the title compound, [Au(C(9)H(9)ClNOS)(C(18)H(15)P)]·0.5CH(2)Cl(2), exists within a slightly distorted linear geometry defined by an S,P donor set [S-Au-P angle = 178.01 (4)°]; a close intra-molecular Au⋯O contact [2.964 (4) Å] also occurs. In the crystal structure, mol-ecules are linked into supra-molecular chains propagating along [010] by C-H⋯N, C-H⋯S and C-H⋯π inter-action...
