Descripción
Sumario:In the title compound [systematic name: bis­(4-meth­oxy-3,4-di­hydro­quinazolin-1-ium) 2,5-di­chloro-3,6-dioxo­cyclo­hexa-1,4-diene-1,4-diolate], 2C(9)H(11)N(2)O(+)·C(6)Cl(2)O(4) (2−), the chloranil­ate anion lies about an inversion center. The 4-meth­oxy-3,4-di­hydro­quinazolin-1-ium cations are linked on both sides of the anion via bifurcated N—H⋯(O,O) and weak C—H⋯O hydrogen bonds, giving a centrosymmetric 2:1 aggregate. The 2:1 aggregates are linked by another N—H⋯O hydrogen bond into a tape running along [1-10]. The tapes are further linked by a C—H⋯O hydrogen bond into a layer parallel to the ab plane.
