| Popis: | The asymmetric unit of the title compound, C10H24N3+·0.5C4H2O42−·0.5C4H4O4, comprises a triisopropylguanidinium cation, half of a fumarate dianion and half of a fumaric acid molecule; both the fumarate dianion and the fumaric acid molecule are located on inversion centres. In the crystal, intermolecular O—H...O hydrogen bonds between the carboxyl groups of the fumaric acid molecules and the carboxylate groups of the fumarate anions lead to the formation of a hydrogen-bonded supramolecular twisted chain along the b axis. The triisopropylguanidinium cations interact with the fumarate–fumaric acid chains via extensive N—H...O and C—H...O hydrogen bonds, leading to a ladder arrangement, with the cation being the rungs that bridge three curled chains of fumarate–fumaric acid. The crystal packing is stabilized by N—H...O and C—H...O (cation...fumarate/fumaric) and O—H...O (fumarate...fumaric) hydrogen bonds, consolidating a three-dimensional network. |
