Tungsten(II) chloride hydrates with high solubility in chloroaluminate ionic liquids for the electrodeposition of Al–W alloy films

In Situ Spectroscopic Identification and DFT-Assisted Prediction of the Valence and Structure of Tungsten Ions in a Cationic/Anionic Molten Salt System

“…The UV−vis spectra of tungsten ions showed bands at 300−400 nm, which were probably d−d transitions, and the first band at 200−300 nm, which might be due to the ligand-to-metal charge transfer. 44,45 The wavelength position of the absorption spectrum of charge transfer depended on the energy difference between the corresponding electron orbit of the electron donor and the electron acceptor. In general, the stronger the oxidation ability of the central ion or the reduction ability of the ligand, the smaller the energy required for the chargetransfer transition, making the wavelength of the absorption spectrum red shift.…”

Additive-free reductive hydrodeoxygenation of fatty acids catalyzed by inexpensive simple nickel(ii) compounds

“…A set of simple Ni ( ii ) compounds was selected to cover various options and combinations of counter-ions, coordination modes, reactivity, and structure (Table 2). Other than Ni(AcO) 2 used for the optimization of the conditions, Ni(AcO) 2 ·4H 2 O was also tested, considering that hydrated salts have been reported to be more reactive than anhydrous ones, 17 along with Ni(acac) 2 , which, as well as has an organic bidentate ligand O-bonded to the Ni ( ii ) atom. As for inorganic Ni ( ii ) compounds, all the NiX 2 halides were used, followed by the oxygen-containing salts Ni(NO 3 ) 2 ·6H 2 O and NiCO 3 .…”

A review on functional nanoarchitectonics nanocomposites based on octahedral metal atom clusters (Nb 6 , Mo 6 , Ta 6 , W 6 , Re 6 ): inorganic 0D and 2D powders and films

“…[268] Another possibility is to use these transition metal atom clusters as precursors for the discovery of new compounds and nanocomposites like nitrides, carbides, borides, sulfides or alloys. [269][270][271][272][273] The field of possibilities is open to everyone and the adventure of the nanocomposites based on metal atom clusters has only just begun. Figure 14.…”
