Metal Complexes and Their Solvent Extraction

Structure and dynamics of solvent shells around photoexcited metal complexes.

Understanding the geometry, energetics and dynamics of solvated transition metal (TM) compounds is decisive in characterizing and optimizing their function. Here, we demonstrate that it is possible to quantify the structural dynamics of solvated [Ru(II)(bpy)3], an important TM-complex for solar-energy harvesting research, by using state-of-the art force fields together with molecular simulation...

Thiosemicarbazones and Their Transition Metal Complexes

Arylazo derivatives of some fluorinated β-diketones and their metal complexes

Phenylazo and benzothiazolylazo derivatives of trifluoroacetylacetone andhexafluoroacetylacetone have been synthesized and characterized. Analytical and spectral datarevealed the existence of phenylazo derivatives in the intramolecularly hydrogen-bonded ketohydrazoneform while the benzothiazolylazo derivatives in the azo-enol form. The monobasicbidentate coordination of the phenylazo derivative...

V). Separation Processes-solvent Extraction/ Ion Exchange for Metal Ions

In the hydrometallurgical processing of complex ores/ concentrates/ secondaries/ wastes, the solutions containing different non-ferrous metals are obtained during teaching the materials in acidic, ammoniacal or alkaline lixiviants. The spent solutions and effluents are also generated in different process industries and contain metallic values. Their discharge in the sewage or river is major con...

Preparation of Symmetrical Tetraphenyl Porphyrin Metal Complexes and Their Spectroscopic Studies

Porphyrins molecules are gaining importance in the present era. Porphyrins are important part of biological molecules like hemoglobin and chlorophyll .Photo system 1 and photo system 2 is important sunlight trap in chloroplast. Electron transport chain is a series of chemical reaction in which energy is formed in the form of ATP (Adenosine triphosphate).The members of electron transport chains ...
