Abstract
In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the SnIV atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetrabutylammonium cation are partially disordered, each with refined site occupancies of 0.691 (6):0.309 (6). Weak C—H⋯Cl hydrogen-bonding interactions help to consolidate the crystal packing, as well as a short Cl⋯Cl interaction of 3.295 (2) Å.
