C5H14NO · ZnCl(HPO3), an unexpected product from an ionic-liquid synthesis

C5H14NO · ZnCl(HPO3) arose from an unexpected reaction in which a component of the ionic liquid mixed solvent was incorporated into a hybrid structure in which cholinium (C5H14NO+) cations interact with [ZnCl(HPO3)]− macroanionic layers by way of O–H⋯O hydrogen bonds. The inorganic layers display a 4 · 82 topology.
