Three new crystalline architectures based on acridinium trifluoromethanesulfonate salts [C13H10N](+)[CF3SO3](-) have been isolated as single crystals from the reaction of the dimeric hydroxo di-n-butylstannane trifluoromethanesulfonato complex [n-Bu2Sn(OH)(H2O)(CF3SO3)](2) (1) with acridine (C13H9N, Acr), in dichloromethane at room temperature. When an equimolar mixture of anthracene (C14H10, Ant) and acridine is initially used, the crystallization of a sandwich-type arrangement occurs, leading to the intercalation of one molecule of anthracene between two acridium trifluoromethanesulfonate salt molecules. In the three X-ray structures reported, the crystal packing involves the contribution of hydrogen bonding and aromatic ring interactions, as well as short contacts of type O center dot center dot center dot(H)C, F center dot center dot center dot(H)C and F center dot center dot center dot F.
