Alkali Uranyl Borates: Bond Length, Equatorial Coordination and 5f States

چکیده
Three uranyl borates, UO2B2O4, LiUO2BO3 and NaUO2BO3, have been prepared by solid state syntheses. The influence of the crystallographic structure on splitting empty 5f 6d states probed using High Energy Resolved Fluorescence Detected X-ray Absorption Spectroscopy (HERFD-XAS) at uranium M4-edge L3-edge respectively. We demonstrate that is increased decrease U-Oax distance, which in turn correlates with an bond covalency. This correlated to equatorial coordination change uranium. role alkalis as charge compensating axial oxygen discussed.

Density functional analysis of the trigonal uranyl equatorial coordination in hexahomotrioxacalix[3]arene-based macrocyclic complexes.
Representative models of the different geometries observed for uranyl complexes with fully deprotonated p-R-hexahomotrioxacalix[3]arene (R = tert-Bu, Me) ligands, among which is the rare trigonal geometry, have been investigated using all-electron scalar relativistic density functional theory (DFT). Optimized structures of complexes incorporating triethylammonium (HNEt3+) and 4-methylpiperidini...
متن کاملTemperature Dependent 5f-states in URu2Si2
A dramatic temperature dependent enhancement of U 5f spectral weight at EF is observed in angle-resolved photoemission measurements of URu2Si2 at the center of an X-point hole-pocket. Comparison of this temperature dependent behavior for excitation both at and below the U 5d→5f resonant threshold is presented.

The geomeffy, bond valences, and polymerization ofhexavalent uranium polyhedra from 105 well-refined structures are analyzed. The Utu cation is almost always present in crystal stnrctures as part of a nearly linear (UOr)z* uranyl ion that is coordinated by four, five or six equatorial anions in an approximately planar arangement perpendicular to the uranyl ion, giving square, pentagonal and hex...
متن کاملBond-length distributions for ions bonded to oxygen: alkali and alkaline-earth metals
Bond-length distributions have been examined for 55 configurations of alkali-metal ions and 29 configurations of alkaline-earth-metal ions bonded to oxygen, for 4859 coordination polyhedra and 38 594 bond distances (alkali metals), and for 3038 coordination polyhedra and 24 487 bond distances (alkaline-earth metals). Bond lengths generally show a positively skewed Gaussian distribution that ori...
متن کاملBoric Acid and Borates
Boric acid and its chemical relatives are pesticides that are derived from the element boron. Boron rarely occurs alone and is typically found in combination with other elements; common combinations are boric acid or borates.1 Unlike many pesticides which are synthetic compounds,2 boric acid and related pesticides are naturally occurring compounds.1 Boron compounds are widely found in rivers, s...
