Abstract

Crystalline dihydrate of hemi-(diazonium-18-crown-6) isocyanurate of isocyanuric acid, 0.5[H2DA18K6]2+⋅(C3H2N3O3)−⋅C3H3N3O3⋅2H2O, was prepared and investigated by X-ray crystallography. In the given structure the dication DA18K6 is center-symmetric and possesses crown conformation of approximate D 3h symmetry. Molecule of isocyanuric acid and its anion are nearly planer. This molecule possesses approximate D 3h symmetry and its anion possesses approximate C 2v symmetry. With sufficient precision were determined geometrical parameters (bond lengths, bond angles etc.) of ions and molecules and was determined their packing in the given crystalline structure in which there is developed system of intermolecular (interion) hydrogen bonds.
