N (1)-(Thio-phen-2-ylmeth-yl)-N (3),N (3)-bis-[3-(thio-phen-2-yl-methyl-ammonio)-prop-yl]propane-1,3-di-ammonium hexa-fluorido-silicate methanol tris-olvate.
In the title compound, C24H40N4S3 (4+)·2SiF6 (2-)·3CH3OH, the central tertiary amine function is protonated and is connected to three thio-phen-2-yl-methyl-amino-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 SiF6 (2-) anion bonded via two N-H⋯F inter-actions with the protonated amine group on the middle arm, while two methanol solvent mol-ecules 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 mol-ecules and between the solvent mol-ecules and the anions, respectively, are also observed. All three thio-phene 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).
