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

9-Aminoacridinium chloride N,N-dimethylformamide monosolvate, C13H11N2+Cl-center dot C3H7NO, crystallizes in the monoclinic space group P2(1)/c. The salt was crystallized from N,N-dimethylformamide. The asymmetric unit consists of two C13H11N2+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 pi-pi interactions between the 9-AA rings, and the whole lattice is additionally stabilized by electrostatic interactions between ions.
