WebThe reaction of MO (M = V, Re) with H2S investigated by spectrophotometry, indicated the existence of two new thioanions VO2S and ReOS. Their spectra are compared with known … WebIn sulfate-reducing environments and where free sulfide is available thioarsenic species are known to exist, yet compared to the oxyanion species of arsenic little is know about the formation, structure, chemistry, and stability of arsenic thioanions in the environment.
WebIt is interesting to note that, in case of metal thioanions of VB group (AsS;- and SbS3 ), Leonard-Jones potential also gives a fairly reasonable set of force constants as shown in … WebAnalytical expressions are derived for determining the symmetry force constants of XY 4 (T d) and XY 3 (d 3h) typs molecules in the orbital valency force field model, which proves to be very useful in the interpretation of the structure and bonding in those molecules.The results obtained are compared with the values of symmetry force constants determined using …
Webionion.com is the first internet portal for Kefalonia & Ithaki. Since 1996 we have helped thousands of visitors to gain information about our two islands. This last updated version … WebRecent discoveries demonstrate that the chemistry of arsenic in sulfidic waters is much more complex that previously believed. One implication is that all earlier thermodynamic data on stabilities of As thioanions require revision. Previously used experimental approaches for determining As thioanion stabilities may be inadequate to deal with the …
WebIdentities of the key ligands are poorly known but probably include thioanions. Here, the first determinations of stability constants for Fe(2+)-[MoS4](2-) complexes in aqueous solution are reported based on measurements of pyrrhotite (hexagonal FeS) solubility under mildly alkaline conditions. Two linear complexes, [FeO(OH)MoS4](3-) and ...
