The title salt, C~8~H~20~NO~5~ ^+^·C~7~H~4~NO~4~ ^−^·H~2~O, is composed of a 4-nitrobenzoate anion, a [2-hydroxy-1,1-bis(hydroxymethyl)ethyl]bis(2-hydroxyethyl)ammonium (NBHHP) cation and a water molecule. The three units are linked by O—H...O hydrogen bonds.
ÁCl À , contains two crystallographically independent cations and two chloride ions. The crystal structure is stabilized by intramolecular O-HÁ Á ÁO, and intermolecular N-HÁ Á ÁCl and O-HÁ Á ÁCl hydrogen bonds.
