Abstract
The crystal structure of the title salt, C(5)H(6)NO(+)·HSO(4) (-), consists of planar(r.m.s. deviation = 0.001 Å) 4-hydroxy-pyridinium cations and hydrogen sulfate anions which are hydrogen bonded into a layer motif. In the anion, the S-O bond [1.551 (2) Å] involving the O atom bearing the acid H atom is longer than the other three S-O bonds, which range from 1.437 (1) to 1.454 (1) Å.
摘要
标题盐C(5)H(6)NO(+)·HSO(4) (-)的晶体结构由平面（均方根偏差 = 0.001 Å）的4-羟基吡啶阳离子和硫酸氢根阴离子组成，它们通过氢键形成层状结构。在阴离子中，与带有酸性H原子的O原子相连的S-O键[1.551 (2) Å]比其他三个S-O键长，其他三个S-O键的长度范围为1.437 (1)至1.454 (1) Å。
