Abstract

The title compound, C13H11NO4·H2O, is a monohydrate of a betaine exhibiting a positively charged N-substituted isoquino­line group and a deprotonated carboxyl group. In the crystal, mol­ecules are connected via short O—H⋯O hydrogen bonds between protonated and deprotonated carboxyl groups into chains of either R or S enanti­omers along [001]. These chains are additionally connected by hydrogen bonding between water mol­ecules and the deprotonated carb­oxy groups of neighbouring mol­ecules.
