Abstract

In the title compound (systematic name: 2,3-dimethoxy-10-oxostrychnidinium 2-carboxy-6-nitrophthalate dihydrate), C23H27N 2O4 +.C8H4NO 6 -.2H2O, the carboxylic acid and carboxylate groups of the hydrogenphthalate anions form head-to-tail catemeric chains of strong intermolecular O-Hâ‹¯O hydrogen bonds [Oâ‹¯O distance = 2.563 (5) Ã…] along the 21 screw axes parallel to the a axis. The chains further associate with the water molecules, forming sheet structures parallel to (010). The protonated N atom at the 19-position of the brucine molecule forms a peripheral intermolecular hydrogen bond with the carboxylate group of the anion. © 2005 International Union of Crystallography Printed in Great Britain - all rights reserved.
