In the title compound, C(20)H(21)N(2) (+)·C(7)H(7)O(4)S(-)·H(2)O, the cation is nearly planar and exists in the E configuration. The cations and anions form individual chains along the b axis and are inter-connected by weak C-H⋯O inter-actions. The 4-methoxy-benzensulfonate anions are linked to water mol-ecules through O-H⋯O hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by a C-H⋯π inter-action involving the methoxy-phenyl ring. The sulfonate anion is also involved in a weak intra-molecular C-H⋯O inter-action which generates an S(5) ring motif.
在标题化合物C₂₀H₂₁N₂⁺·C₇H₇O₄S⁻·H₂O中，阳离子近乎平面，呈E构型。阳离子和阴离子沿b轴形成单独的链，并通过弱C-H⋯O相互作用相互连接。4-甲氧基苯磺酸根阴离子通过O-H⋯O氢键与水分子相连，形成三维网络。晶体结构通过涉及甲氧基苯环的C-H⋯π相互作用进一步稳定。磺酸根阴离子还参与了一个弱的分子内C-H⋯O相互作用，形成了一个S(5)环 motif。
