There are two cations and two anions in the asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·HSeO(4) (-). In the crystal, there are two independent chains of HSeO(4) (-) anions running along the a axis, linked by O-H⋯O hydrogen bonds. Ribbons of cations linked by N-H⋯O hydrogen bonds run along the b-axis direction, and are further hydrogen bonded to the anions by N-H⋯O and C-H⋯O links, generating a three-dimensional network.
标题化合物C(5)H(6)N(3)O(2) (+)·HSeO(4) (-)的不对称单元中有两个阳离子和两个阴离子。在晶体中，有两条独立的沿a轴延伸的HSeO(4) (-)阴离子链，通过O-H⋯O氢键相连。由N-H⋯O氢键连接的阳离子带沿b轴方向延伸，并通过N-H⋯O和C-H⋯O连接进一步与阴离子形成氢键，形成三维网络。
