A set of effective ionic radii corresponding to different coordination numbers (CNs) and compatible with the radii system by Shannon [Acta Cryst. (1976), A32, 751-767] has been derived for ammonium: 1.40 Å (CN = IV), 1.48 Å (CN = VI), 1.54 Å (CN = VIII) and 1.67 Å (CN = XII). The bond-valence parameters r0 = 2.3433 Å and B = 0.262 Å have been determined for ammonium-fluorine bonds.
已经推导出了一组与不同配位数（CN）相对应且与香农[《晶体学报》（1976年），A32，751 - 767]的半径系统兼容的铵离子有效离子半径：1.40 Å（CN = IV）、1.48 Å（CN = VI）、1.54 Å（CN = VIII）和1.67 Å（CN = XII）。已确定铵 - 氟键的键价参数r0 = 2.3433 Å和B = 0.262 Å。
