In the title hydrated mol-ecular salt, C(18)H(23)N(2) (+)·C(6)H(4)ClO(3)S(-)·H(2)O, which shows moderate biological activity against methicillin-resistant Staphylococcus aureus (MRSA), one ethyl group of the 2-[4-(diethyl-amino)-styr-yl]-1-methyl-pyridinium cation is disordered over two orientations in a 0.604 (13):0.396 (13) ratio. The main part of the cation is nearly planar with a dihedral angle of 4.50 (10)° between the pyridinium and benzene rings. In the crystal, the components are linked by O-H⋯O hydrogen bonds and C-H⋯O weak inter-actions. Aromatic π-π stacking inter-actions with centroid-centroid separations of 3.7363 (12) and 3.7490 (13) Å also occur.
在标题水合分子盐C(18)H(23)N(2)(+)·C(6)H(4)ClO(3)S(-)·H(2)O中，其对耐甲氧西林金黄色葡萄球菌（MRSA）显示出适度的生物活性，2-[4-(二乙氨基)-苯乙烯基]-1-甲基吡啶阳离子的一个乙基在两个取向上无序排列，比例为0.604 (13):0.396 (13)。阳离子的主要部分近乎平面，吡啶环和苯环之间的二面角为4.50 (10)°。在晶体中，各组分通过O-H⋯O氢键和C-H⋯O弱相互作用相连。还存在质心间距为3.7363 (12)和3.7490 (13) Å的芳香π-π堆积相互作用。
