1,3-Bis(4-tert-butylbenzyl)-4,5-dihydroimidazolium chloride monohydrate

Abstract

In the title compound, C25H35N2+·Cl−·H2O, the imidazolidine ring adopts a twisted conformation, with a pseudo-twofold axis passing through the N—C—N carbon and the opposite C—C bond. The N—C—N fragment of the imidazolidine ring shows some degree of both double- and single-bond character due to partial electron delocalization. One of the tert-butyl groups is disordered over two conformations with occupancies of 0.714 (8) and 0.286 (8). In the crystal, O—H...Cl and C—H...O hydrogen bonds help to establish the packing.
