Abstract: In the title compound, C24H40N4S34+·2SiF62-·3CH3OH, the central tertiary amine function is protonated and is connected to three thiophen-2-ylmethylamino-n-propyl groups, forming the arms of a T-shaped cation that has two pockets. Each arm contains one protonated secondary amine function, and each pocket is occupied by one SiF62- anion bonded via two N-HF interactions with the protonated amine group on the middle arm, while two methanol solvent molecules are N-HO hydrogen-bonded with the other secondary protonated amine groups on the side arms. Weak O-HO and O-HF hydrogen bonds between the solvent molecules and between the solvent molecules and the anions, respectively, are also observed. All three thiophene groups in the arms are disordered over two sets of sites, with occupancy ratios of 0.828 (3):0.172 (3), 0.910 (2):0.090 (2) and 0.890 (3):0.110 (3).
