These effects correlate with the charge of the gold atom coordinated to phosphorus. Our investigation shows the high potential of fluorination as a strategy for the modulation of the properties of gold compounds, for example in catalysis, and the applicability of quantum chemical topology studies in...
compounds of the type Ru(bpy)2(NCS)2 (bpy = bypyridine or a derivative; NCS = N-bonded thiocyanate) has been integral to the success in the development of Grätzel-type photoelectrochemical solar cells6,7 that have achieved photon-to-electric current conversion consistently in excess of 10...

The concentration stability constants for CuS04 in various mixed solvents, viz ethanol-water, isopropa-nol-water and dioxane-water, having a composition of organic solvent of 0, 5, 10, 15,20 and 25 mass per cent were measured spectrophotometrically at 298 ±0.5 K using NaC104 as supporting...
Ans:Werner's theory is the first theory to explain the nature of bonding in coordination compounds. The main postulates of this theory are: (i) Two types of valencies, primary and secondary valencies, are present in coordinated compound metals. ...
{NaP5W30O110} can coordinate internally and externally, (c) presence of 30 surface oxygen as external binding sites, (d) stability in long pH range (1–10), (e) Preyssler POM can be a good acid as well as redox catalyst, (f) unique structural symmetry of the ligand field, low ...
27 A Bayesian error estimation functional (mBEEF) systematically improves PBE results reaching an MAE of about 120 meV/atom for a test set of 24 compounds.28 Applying a correction method on top of the functional could reduce the MAE to 90 meV/atom, which is 20–60 meV/atom less ...
lead to electrostatic adsorption on the surface of the CS and the formation of an insoluble layer that slows down the dissolution of CS. Using a suitable isothermal technique, the adsorption conditions of the synthesized compounds on the CS surface may be established. To ascertain whether ...
