Proton ordering in (NH4)3H(SO4)2 at low‐temperature phase transitions

Single‐crystal neutron diffraction was used to investigate the H‐atom disorder in triammonium hydrogen disulfate (TAHS), (NH4)3H(SO4)2, below room temperature. Crystal structure analysis of the monoclinic phase III shows an increase of proton ordering with decreasing temperature in the (SO4)H(SO4) d...
