New acridinium trifluoromethanesulfonate stacks induced in the presence of organotin(IV) complexes

摘要

Three new crystalline architectures based on acridinium trifluoromethanesulfonate salts [C_(13)H_(10)N]~+[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 (C_(13)H9N, Acr), in dichloromethane at room temperature. When an equimolar mixture of anthracene (C_(14)H_(10), 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 ···(H)C, F···(H)C and F···F.
