摘要：

The crystal structure of ammonium dihydrogen arsenate NH4H2AsO4 (ADA) is analyzed in the paraelectric (PE) and antiferroelectric (AFE) phases. In the PE phase the As atom has two equilibrium positions along the c axis and single minimum position along the a(b) axis. In the AFE phase, the atomic configuration of the As, N, O, and H atoms of the H2AsO4 ions is compatible with the AFE order (Nagamiya's model), and the AFE distortion of the AsO4 tetrahedron and the position of the N atom do not depend on temperature remarkably.
