Research output: Contribution to journalArticlepeer-review


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], 2C9H11N2O+·C 6Cl2O4 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.
