The square-planar complex [bis(toluene-3,4-dithiolato)copper(iii)][NEt3H], characterised by X-ray photoelectron spectroscopy and DFT, fragments in FTICR-MS to form [(toluene-3,4-dithiolato)Cu(iii)(peroxide)]− by reaction with O2.

Abstract Starting from pentaglycerin, H3CC(CH2OH)3, a convenient three step synthesis of the tri­pod ligand H3CC(CH2PPh2)2(CH2OH) (3) (abbreviated as PPO(H)) is described and its struc­ture is established by the usual analytical methods as well as by X-ray analysis. The ligand behaves as a bidentate donor towards nickel(II) as shown by the formation and X-ray analysis of the complex {PPO(H)}NiBr2 (4). In the square planar complex 4 only the PPh2 groups are coordinated. In the tetrahedral complex [{PPO(H)}2Ni](BF4)2 (5) two PPO(H) ligands sur­round nickel as bidentate ligands.

A single-crystal X-ray structure determination of the reagent (butane-1,4-diyl)(N,N,N′,N′- tetramethylethylenediamine)palladium(II) has shown that crystals are orthorhombic, Pbca, a 15.832(3), b 14.128(9), c 11.451(3) Ǻ, Z 8. The square planar complex has puckered PdCH2CH2CH2CH2 and PdNMe2CH2CH2NMe2 rings in which the outer carbon atoms deviate by c. �0.35 Ǻ from the 'PdC2N2' mean plane.

AbstractHf metal thin films were deposited on Si substrates using a pulsed laser deposition technique in vacuum and in ammonia ambients. The films were then oxidized at 400 °C in 300 Torr of O2. Half the samples were oxidized in the presence of ultraviolet (UV) radiation from a Hg lamp array. X-ray photoelectron spectroscopy, atomic force microscopy, and grazing angle X-ray diffraction were used to compare the crystallinity, roughness, and composition of the films. It has been found that UV radiation causes roughening of the films and also promotes crystallization at lower temperatures.Furthermore, increased silicon oxidation at the interface was noted with the UVirradiated samples and was shown to be in the form of a mixed layer using angle-resolved X-ray photoelectron spectroscopy. Incorporation of nitrogen into the film reduces the oxidation of the silicon interface.

AbstractGe is deposited on HfO2 surfaces by chemical vapor deposition (CVD) with GeH4. 0.7-1.0 ML GeHx (x = 0-3) is deposited by thermally cracking GeH4 on a hot tungsten filament. Ge oxidation and bonding are studied at 300-1000 K with X-ray photoelectron spectroscopy (XPS). Ge, GeH, GeO, and GeO2 desorption are measured with temperature programmed desorption (TPD) at 400-1000 K. Ge initially reacts with the dielectric forming an oxide layer followed by Ge deposition and formation of nanocrystals in CVD at 870 K. 0.7-1.0 ML GeHx deposited by cracking rapidly forms a contacting oxide layer on HfO2 that is stable from 300-800 K. Ge is fully removed from the HfO2 surface after annealing to 1000 K. These results help explain the stability of Ge nanocrystals in contact with HfO2.
