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.

Ethanolic solutions containing (NBu4)HSO4 (1.26 g, 4 mmol) and SnBuCl3 2.25 g, 8 mmol) were mixed and stirred at room temperature for more than 1 h. After removing the precipitate, the filtrate was allowed to evaporate to give colourless crystals of the title compound. The idealized overall reaction is: (NBu4)HSO4 + 2 SnBuCl3 → (NBu4)[SnBuCl4] + SnBuCl2HSO4
Three reflections, (0 1 1), (1 0 0) and (1 1 1), were obstructed by the beam stop and were omitted from the Disorder is observed for the dibutyl ammonium ion. Two of the four butyl chains of the tetrabutylammonium cation are partially disordered and were refined with site occupancies of 0.691 (6):0.309 (6) for each chain. All equivalent disordered moieties were restrained to have similar geometries. The displacement parameters of disordered atoms C12, C121, C24 and C241 of the tetrabutylammonium cation were restrained to be approximately isotropic. The H atoms were initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H in the range 0.93–0.98, Å) and Uiso(H) (in the range 1.2–1.5 times Ueq of the parent atom), after which the positions were refined with riding constraints.

The interest in new organotin(IV) derivatives is related to their applications in different fields: stabilization of polyvinyl chloride, treatments for glass surface, homogeneous catalysts, textile treatments and fungicidal properties (Evans & Karpel, 1985; Davies et al., 2008).
The asymmetric unit of the title compound, (N(C4H9)4)[Sn(C4H9)Cl4], is illustrated in Fig. 1. It consists of a tetrabutylammonium cation and a tetrachloridobutylstannate(IV) anion. The Sn(IV) atom is five-coordinated in a distorted trigonal-bipyramidal arrangement with Cl4 and Cl5 in the apical positions. Major bond angle deviations with respect to the ideal trigonal-bipyramidal coordination geometry appear to be related to the different sizes of the butyl group and the Cl atoms. Thus in the equitorial plane, the C6—Sn1—Cl2 angle (125.04 (15)°) is larger than the Cl2—Sn1—Cl3 angle (112.46 (6)°). The angle Cl4—Sn1—Cl5 is 175.24 (6)°, indicating a slight deviation from linearity. The local geometry at the Sn(IV) position in the title compound is thus similar to that in (Ph4As)[MeSnCl4] (Webster et al., 1976). The Sn—Cl distances, [2.3390 (12), 2.3494 (14), 2.4812 (14) and 2.5051 (14) Å], are slightly outside the range of the Sn—Cl distances [2.369 (4) and 2.400 (4) Å] observed in (n-Pr2NH2)[Sn(C2O4)Cl4] (Sow et al., 2010). The C—N—C angles of the cation are close to 109°, in agreement with the expected sp3 hybridization.
The packing of the structure is shown in Fig. 2. A short intermolecular Cl2···Cl2 interaction of 3.295 (2) Å is found between two SnBuCl4- anions related by an inversion center. Only two other non-disordered compounds containing chloridotin(IV) complexes have shorter Cl···Cl intermolecular interactions: 3.190 Å in [C33H25N3SnCl4]·CH2Cl2 (Brazeau et al., 2012); 3.288 Å in trans-[PdCl(SnCl3(2-PyPPh2)2)] (Cabon et al., 2010). In the title compound, cations and anions stack along the a-axis and are connected via weak C—H···Cl hydrogen-bonding interactions (Fig. 2). The stacks themselves are connected via weak Cl···Cl interactions and another C—H···Cl interaction as to form sheets parallel to the ab plane.
