Silver(I,III) oxide
open-in-new
<h2 id="structure">Structure</h2> <p>Although its <a href="/facts/Empirical_formula/xd0vSIlm">empirical formula</a>, AgO, suggests that the compound tetrasilver tetraoxide has silver in the +2 <a href="/facts/Oxidation_state/W53W6s6V">oxidation state</a>, each unit has two monovalent silver atoms bonded to an oxygen atom, and two trivalent silver atoms bonded to three oxygen atoms, and it is in fact <a href="/facts/Diamagnetism/dgFavn9K">diamagnetic</a>. <a href="/facts/X-ray_diffraction/WtI0F5DN">X-ray diffraction</a> studies show that the silver atoms adopt two different coordination environments, one having two collinear oxide neighbours and the other four coplanar oxide neighbours.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> tetrasilver tetraoxide is therefore formulated as AgIAgIIIO2<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> or Ag2O·Ag2O3. It has previously been called silver peroxide, which is incorrect since it does not contain the <a href="/facts/Peroxide/VMU8y4xB">peroxide</a> ion, O22−. </p> <h2 id="uses">Uses</h2> <p>Tetrasilver tetroxide has been marketed under a trade name "Tetrasil." In 2010, the FDA issued a warning letter to an American company concerning the firm's marketing of Tetrasil and Genisil ointments of tetrasilver tetroxide for <a href="/facts/Herpes/8AQktlTV">herpes</a> and similar conditions.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Wells A.F.
