Silver(II) complexes tend to be more common. Like the valence isoelectronic copper(II) complexes, they tend to be square planar and paramagnetic, that is enhanced through the better field splitting for 4d electrons than for 3d electrons. Aqueous Ag2+, made by oxidation of Ag+ by ozone, is a very powerful oxidising https://jaideneknqu.birderswiki.com/747729/the_silber_diaries
