Thorium divanadate dihydrate, Th(V2O7)(H2O)2
The title compound, Th(V(2)O(7))(H(2)O)(2), was synthesized by a hydro-thermal reaction. The crystal structure consists of ThO(7)(OH(2))(2) tricapped trigonal prisms that share edges, forming [ThO(5)(OH(2))(2)](n) chains along [010]. The edge-sharing ThO(7)(OH(2))(2) polyhedra share one edge and five vertices with the V(2)O(7) divanadate anions having a nearly ecliptic conformation parallel to ...
متن کاملThorium and Iron Content of Mine Dusts
The thorium content of mine dust collected at various locations along the drift to the SNO site has been measured with several techniques-direct counting, proton induced x-ray emission, x-ray fluorescence, and neutron activation analysis. The thorium content varies significantly, from a minimum of 4 ppm to a maximum of 24 ppm (from direct counting measurements). The average Th content of the si...
متن کاملProperties of the Only Thorium Fullerene, Th@C84, Uncovered.
Only a single thorium fullerene, Th@C84, has been reported to date (Akiyama, K.; et al. J. Nucl. Radiochem. Sci. 2002, 3, 151-154). Although the system was characterized by UV-vis and XANES (X-ray absorption near edge structure) spectra, its structure and properties remain unknown. In this work we used the density functional calculations to identify molecular and electronic structure of the Th@...
متن کاملRole of Iron (Fe) in Body
Iron is an essential element for most life on Earth, including human beings by participating in a wide variety of metabolic processes, including oxygen transport, DNA synthesis, and electron transport. Iron is needed for a number of highly complex processes that continuously take place on a molecular level and that are indispensable to human life, e.g. the transportation of oxygen around your b...
متن کاملThe Th=C double bond: an experimental and computational study of thorium poly-carbene complexes.
The first thorium poly-carbene complexes [(Ph(2)P=S)(2)C](2)Th(DME) (2) and [{[(Ph(2)P=S)(2)C](3)Th}Li(2)(DME)](n) (3) have been prepared and structurally characterized. DFT calculations reveal that the Th=C bond is polarized toward the nucleophilic carbene carbon atom, which is further verified by the experimental observation that the Th=C bond shows a nucleophilic behavior with Ph(2)CO.
