Description
The determination of the atomic positions and thermal parameters of the crystal structure for phase II of β-LiNH4SO4 is carried out by the single crystal neutron diffraction at room temperature for the purpose to refine N-H bond lengths for ammonium ions. The acquisition of intensities from Bragg reflections is fulfilled on the E5 diffractometer set in BENSC (HMI, Berlin, Germany). Atomic positions and thermal parameters are determined by the least-square method with R = 0.072 and wR = 0.057. It is shown that ammonium ions can be presented as regular tetrahedra
