چکیده
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).

There are two independent mol-ecules in the asymmetric unit of the title compound, C(16)H(11)BrN(2)S(2). In the crystal, weak C-H⋯N hydrogen bonds and C-H⋯thio-phene ring inter-actions link the mol-ecules into chains along [100]. The structure exhibits disorder of the 2-thio-phen-2-yl substituent of one of the symmetry-unique mol-ecules with a major:minor component ratio of 0.914 (3):0.086 (3).
