The title acid, 8-aminooctanoic acid, C8H17NO2, crystallized in the centrosymmetric space group P2(1)/n in the zwitterionic form. The three H atoms involved in hydrogen bonding are ordered. The five intermolecular N-H...O hydrogen bonds have N...O distances ranging from 2.752 (2) to 3.258 (2) A and N-H...O angles ranging from 131 (2) to 165 (2) degrees. Each molecule is linked to six neighboring molecules by a total of ten hydrogen bonds. A complex network of hydrogen bonds ensues in which chains predominate.
标题酸，8-氨基辛酸，C8H17NO2，以两性离子形式结晶于中心对称空间群P2(1)/n中。参与氢键形成的三个氢原子是有序的。五个分子间N-H...O氢键的N...O距离在2.752(2)至3.258(2) Å之间，N-H...O角度在131(2)至165(2)度之间。每个分子通过总共十个氢键与六个相邻分子相连。由此形成了一个以链为主的复杂氢键网络。
