Crystal structure of 9-amino­acridinium chloride N,N-di­methyl­formamide monosolvate

9-Amino­acridinium chloride N,N-di­methyl­formamide monosolvate, C(13)H(11)N(2) (+)Cl(−)·C(3)H(7)NO, crystallizes in the monoclinic space group P2(1)/c. The salt was crystallized from N,N-di­methyl­formamide. The asymmetric unit consists of two C(13)H(11)N(2) (+)Cl(−) formula units. The 9-amino­acridinium (9-AA) mol­ecules are protonated with the proton on the N atom of the central ring. This N atom is connected to an N,N-di­methyl­formamide mol­ecule by a hydrogen bond. The H atoms of the amino groups create short contacts with two chloride ions. The 9-AA cations in adjacent layers are oriented in an anti­parallel manner. The mol­ecules are linked via a network of multidirectional π–π inter­actions between the 9-AA rings, and the whole lattice is additionally stabilized by electrostatic inter­actions between ions.
