Bis[2-(4-aminophenyl)-4,5-dihydro-1H-imidazol-3-ium] dichloride monohydrate

Abstract

The asymmetric unit of the title compound, 2C9H12N3+·2Cl−·H2O, comprises two molecules, two chloride anions and one molecule of crystal water. In the imidazolinium ring, the protonation contributes to delocalization of the positive charge over the two C—N bonds. Both chloride anions are acceptors of four hydrogen bonds in a flattened tetrahedron environment. The donors are NH2 groups, the NH groups of the imidazolinium rings and the water molecule. These hydrogen bonds and N—H...O(H2O) hydrogen bonds form a three-dimensional network.
