Abstract

The crystal structures of diammonium fumarate, 2NH4+.C4H2O42- (I), and bis(isopropylammonium) fumarate, 2C3H7NH3+.C4H 2O42-, (II), have been determined. The intermolecular N-H⋯O hydrogen bonds form a three-dimensional network in (I), whereas two-dimensional sheets are formed in (II) separated by layers of isopropyl groups. The N⋯O distances are 2.790 (1)-2.903 (1) Å in (I) and 2.747 (1)-2.807 (1) Å in (II). Differences between the solid-state photoreactivities of the fumaric acid ions in (I) and (II) are rationalized based on the crystal structures.
