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-H...F inter­actions with the protonated amine group on the middle arm, while two methanol solvent mol­ecules are N-H...O hydrogen-bonded with the other secondary protonated amine groups on the side arms. Weak O-H...O and O-H...F 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).
