The asymmetric unit includes two crystallographically independent equivalents of the title salt, C(6)H(7)N(2)O(2) (+)·ClO(4) (-). The cations and anions form separate layers alternating along the c axis, which are linked by N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds into a two-dimensional network parallel to (100). Further C-H⋯O contacts connect these layers, forming a three-dimensional network, in which R(4) (4)(20) rings and C(2) (2)(11) infinite chains can be identified.
不对称单元包含两个标题盐C(6)H(7)N(2)O(2) (+)·ClO(4) (-)的晶体学独立等效物。阳离子和阴离子沿c轴交替形成单独的层,这些层通过N-H⋯O、O-H⋯O和C-H⋯O氢键连接成平行于(100)的二维网络。进一步的C-H⋯O接触连接这些层,形成三维网络,其中可以识别出R(4) (4)(20)环和C(2) (2)(11)无限链。
