In the two title compounds, cytosinium hydrogen sulfate, C(4)H(6)N(3)O(+).HSO(4)(-), (I), and cytosinium perchlorate, C(4)H(6)N(3)O(+).ClO(4)(-), (II), the asymmetric units comprise a cytosinium cation with hydrogen sulfate and perchlorate anions, respectively. The crystal structures of (I) and (II) are similar; that of (I) is characterized by a three-dimensional N-H...O, O-H...O and C-H...O hydrogen-bonded network. In (I) and (II), two-dimensional layers are formed by N-H...O and C-H...O hydrogen bonds and, in the case of (I), they are linked by O-H...O hydrogen bonds where the anion acts as a donor and the cation as an acceptor. The hydrogen-bonded sheets in (II) form an angle of 87.1 degrees.
在两种标题化合物中，硫酸氢胞嘧啶鎓（C₄H₆N₃O⁺·HSO₄⁻），（I），和高氯酸胞嘧啶鎓（C₄H₆N₃O⁺·ClO₄⁻），（II）中，不对称单元分别包含一个带有硫酸氢根和高氯酸根阴离子的胞嘧啶鎓阳离子。（I）和（II）的晶体结构相似；（I）的晶体结构的特征是三维的N-H...O、O-H...O和C-H...O氢键网络。在（I）和（II）中，二维层由N-H...O和C-H...O氢键形成，并且在（I）的情况下，它们通过O-H...O氢键相连，其中阴离子作为供体，阳离子作为受体。（II）中的氢键片层形成87.1度的夹角。
