| Abstract: | Highly effective exaction (up to 97%) of noble metal Au, Pt, or Pd as MCl4n? form (i.e., AuCl4?, PtCl42?, or PdCl42?) from NanMCl4 aqueous solution have been achieved on the basis of the interactions between MCl4n? and cyclo2](2,6-di(1H-imidazol-1-yl)pyridine)2](2,6-bisbromomethyl)pyridine (14+). |
