Definitely The main oxidation point out for silver in complexes is +1. The Ag+ cation is diamagnetic, like website its homologues Cu+ and Au+, as all a few have closed-shell electron configurations without having unpaired electrons: its complexes are colourless presented the ligands aren't much too very easily polarized such as I−. Ag+ kinds salts with most anions, but it is hesitant to coordinate to oxygen and thus These types of salts are insoluble in water: the exceptions tend to be the nitrate, perchlorate, and fluoride. The tetracoordinate tetrahedral aqueous ion [Ag(H2O)4]+ is thought, but the attribute geometry for the Ag+ cation is 2-coordinate linear.
