TDS Sodium Stannate.pdf
Sodium stannate (CAS:12209-98-2) is the inorganic compound with the formula Na2Sn(OH)6. This colourless salt forms upon dissolving tin or tin dioxide in sodium hydroxide. The anion is octahedral as are most stannates, e.g., the hexachlorostannate anion [SnCl6]2−. The Sn-O distances average 2.071 Å.[4] In some old literature, stannates are sometimes represented as the simple oxyanion SnO32−.
