Antimonate
open-in-new
<p>In chemistry an antimonate is a compound which contains a <a href="/facts/Metallic_element/PT8hNX6R">metallic element</a>, <a href="/facts/Oxygen/acyn6o8r">oxygen</a>, and <a href="/facts/Antimony/YsA7lVgT">antimony</a> in an <a href="/facts/Oxidation_state/W53W6s6V">oxidation state</a> of +5. These compounds adopt polymeric structures with M-O-Sb linkages. They can be considered to be derivatives of the hypothetical <a href="/facts/Antimonic_acid/YsA7lVgT">antimonic acid</a> H3SbO4, or combinations of <a href="/facts/Metal_oxide/DXtoVe1C">metal oxides</a> and <a href="/facts/Antimony_pentoxide/0uUFFAER">antimony pentoxide</a>, Sb2O5. </p><p>Historically these compounds were assumed to be analogous to the phosphates and formulas such as LiSbO3·3H2O and Na2H2Sb2O7·5H2O were used and the compounds described as hydrated meta-antimonates and pyro-antimonates. LiSbO3·3H2O is now known to be LiSb(OH)6 and contain the Sb(OH)−6 anion and that Na2H2Sb2O7·5H2O is actually NaSb(OH)6. </p>
