| Abstract: | A series of nonempirical calculations by the Hartree-Fock method with full geometry optimization for a number of N- and N,N'-derivatives of thioamides which are potential functional groups for sorbents for extraction of platinum metals from technological solutions. The ligands all prefer to coordinate to platinum metal ions by the sulfur atom (soft Lewis base) at an angle to the sulfur-oxygen bond. |
