Ammonium hydrogenselenate(IV)

M. Weil

Abstract: The title compound, NH₄(HSeO₃), is isostructural with KHSeO₃ and contains tetrahedral NH₄⁺ cations and trigonal-pyramidal HSeO₃^- anions, the latter containing two short Se-O bonds and one long Se-OH bond. The crystal packing is consolidated by a network of weak hydrogen bonds, with donor-acceptor distances (NO and OO) lying between 2.80 and 3.07 Å.
