8-Hy­droxy­quinolin-1-ium hydrogen sulfate monohydrate

TLDR: In the crystal structure of the title salt hydrate, C9H8NO+·HSO4 −·H2O, the quinoline N—H atoms are hydrogen bonded to the bisulfate anions, creating a three-dimensional network in which two R 4 4(12) rings and C 2 2(13) infinite chains can be identified.

Abstract: In the crystal structure of the title salt hydrate, C9H8NO+·HSO4−·H2O, the quinoline N—H atoms are hydrogen bonded to the bis­ulfate anions. The bis­ulfate anions and water mol­ecules are linked together by O—H⋯O hydrogen-bonding inter­actions. The cations and anions form separate layers alternating along the c axis, which are linked by N—H⋯O and O—H⋯O hydrogen bonds into a two-dimensional network parallel to (100). Further O—H⋯O contacts connect these layers, forming a three-dimensional network, in which two R44(12) rings and C22(13) infinite chains can be identified.
