The hydrates of Cu+, Ag+, CuS-, AgS-, Cu2S, and Ag2S were investigated with density functional theory (DFT), solvent field, and atoms-in-molecules (QTAIM) calculations. We found that covalent bonding of the first-shell water molecules to the metals plays a significant role in the total solvation energy. Molecular graphs were obtained and the bonding(More)
Possible mechanisms for degrading chloromethylmercury (CH(3)HgCl) and dimethylmercury [(CH3)2Hg] involving thiol and ammonium residues were investigated by DFT and atoms-in-molecules (QTAIM) calculations. Using H2S and HS- as models for thiol and thiolate groups RSH and RS-, respectively, we obtained transition states and energy barriers for possible(More)
The substitution of Cu2+ by Ag+ in hydrated CuIIS and (CuII)3S3 was modeled computationally by density functional theory quantum theory of atoms in molecules, and solvent field methods. The coordination, first-shell and partly second-shell molecular structures, and thermochemical data for solvated Cu2+, Ag+, CuIIS, (CuII)3S3, AgCu2S3 and their reactions(More)
