The asymmetric unit in the title salt, (C8H20N)2[SnCl4(C7H4Cl2F3)2], features a di-isobutylammonium cation in a general position and a diorganotin tetrachloride dianion, i.e. tetrachloridobis(3-trifuoromethylphenyl)stannate(IV), located on a centre of inversion; the SnIV atom is octahedrally coordinated. In the crystal, charge-assisted N+—H...Cl hydrogen bonds along with C—H...F contacts occur within supramolecular layers that interdigitate along the a-axis direction.
