The asymmetric unit of the title compound, [{Sn(C4H9)2(C6H5COO)}2O]2, consists of two half molecules, completed by application of inversion symmetry. Both mol­ecules adopt a ladder structure typical for this class of dimeric tetra­organodistannoxane di­carboxyl­ates characterized by a centrosymmetric four-membered (Sn—O)2 ring of rhomboidal shape that is extended on both sides by folded six-membered Sn—O—C rings. To a first approximation, both kinds of Sn atoms (Sni and Sno) are trigonal–bipyramidally coordinated. The bond angles between the n-butyl groups are widened [135.64 (7)–146.20 (7)°] in comparison with an ideal trigonal bipyramid. Sn—O bond lengths within the {R2SnO3} coordination sphere depend strongly on the position of the corresponding O atom – axial (ax) or equatorial (eq) – as well as on the functionality of the carboxyl­ate groups which exhibit μ2 (–COOi) and μ1 (–COOo) coordination modes, respectively. In summary, the following sequence of distances [mean values] is found: d(Sno—Oμ3)eq [2.024 (2) Å] < d(Sni—Oμ3)eq [2.044 (2) Å] < d(Sni—Oμ3)ax [2.158 (6) Å] < d(Sno—Oμ1-carb)ax [2.182 (6) Å] < d(Sni—Oμ2-carb)ax [2.250 (2) Å] ≃ d(Sno—Oμ2-carb)ax [2.247 (12) Å]. The n-butyl groups adopt an anti–anti conformation with exception of two disordered outer n-butyl groups of the second mol­ecule which exhibit gauche–anti and anti–gauche conformations. Weak intra­molecular Sn⋯O inter­actions between the different O atoms of the outer carboxyl groups with the inner, as well as outer, Sn atoms give rise to a strongly distorted octa­hedral coordination at these Sn atoms. Inter­molecular inter­actions between the individual mol­ecules are restricted to van der Waals and O⋯H—C inter­actions of which a nearly linear very short C—H⋯O contact between the H atom of the phenyl group of one of the mol­ecules with the outer non-coordinating C=O group of the other molecule is the most prominent. It gives rise to a chain-like arrangement of the mol­ecules along [111]. The two n-butyl groups attached to the outer Sn atom of one mol­ecule are disordered over two sets of sites with occupancies of 0.806 (3)/0.194 (3) and 0.702 (3)/0.298 (3).

1. Chemical context

Our focus on organotin(IV) carboxyl­ates is due to the variety of architectures and the diverse applications displayed by those compounds (Davies, 1997[Davies, A. G. (1997). In Organotin Chemistry. Weinheim: VCH.]; Chandrasekhar et al., 2008[Chandrasekhar, V., Singh, P. & Gopal, K. (2008). Organotin Carboxylate and Sulfonate Clusters. In Tin Chemistry - Fundamentals, Frontiers, and Applications edited by A. G. Davies, M. Gielen, K. H. Pannell & E. R. T. Tiekink. New York: John Wiley & Sons.]). In our search of new structures displayed by these compounds and their derivatives, we recently reported the structure of monomeric di-n-butyl­tin (IV) dibenzoate, nBu2Sn(OOCPh)2 (Reuter & Okio, 2016[Reuter, H. & Okio, C. K. Y. A. (2016). Acta Cryst. E72, 897-900.]), with the tin atom sixfold coordinated via intra­molecular complexation. While that compound has been synthesized by the reaction of di-n-butyl­tin(IV) oxide, nBu2SnO, with benzoic acid, PhCOOH, in a molar ratio of 1:2, we herein present the structure of [{nBu2Sn(OOCPh)}2O]2 obtained from the same reactants using a molar ratio of 1:1.

2. Structural commentary

The title compound (Fig. 1[link]) crystallizes with two formula units [{nBu2Sn(OOCPh)}2O]2 in space group P[\overline{1}]. The asymmetric unit consists of one formula unit composed of two half molecules, completed by application of inversion symmetry (Fig. 1[link]). With the exception of both n-butyl groups attached to the outer Sn atom (Sn4) of the second mol­ecule, all parts of the structure are well ordered. The disorder of the two n-butyl groups was managed by a split model with site occupancies of 0.806 (3)/0.194 (3) and 0.702 (3)/0.298 (3). No further consideration will be made for the structural parameters of those n-butyl groups. It is noteworthy, however, that this disorder is caused by the conformational flexibility of the n-butyl group which adopts – in the case of the major/minor components – a gaucheanti/anti–gauche and anti-gauche/anti–gauche conformation with respect to the Sn—CαCβ—Cγ and Cα—CβCγ—Cδ torsion angles (Fig. 2[link]b,c). This conformation of the disordered n-butyl groups is in contrast to the conformation of all other n-butyl groups of both dimers, which show exclusively an antianti conformation (Fig. 2[link]a). Structural parameters (Table 1[link]) within the ordered n-butyl groups follow the general trends: d(C—C)mean = 1.521 (6) Å, 〈(C—Cβ/γ—C)mean = 112.6 (11)° while bond angles at Cα range from 112.5 (1) to 123.1 (1)°. Sn—C distances are in the range of 2.127 (2)–2.134 (2) Å, mean value 2.130 (3) Å.

The Sn–O framework of both mol­ecules adopts the ladder structure typical for this class of tetra­organodistannoxane di­carboxyl­ates (Chandrasekhar et al., 2008[Chandrasekhar, V., Singh, P. & Gopal, K. (2008). Organotin Carboxylate and Sulfonate Clusters. In Tin Chemistry - Fundamentals, Frontiers, and Applications edited by A. G. Davies, M. Gielen, K. H. Pannell & E. R. T. Tiekink. New York: John Wiley & Sons.]). This ladder-type structure is characterized by a central, four-membered (Sn–O)2 ring on both sides extended by six-membered Sn–O–C rings. Its two inner (Sni) and two outer (Sno) tin atoms are – to a first approximation – fivefold, trigonal–bipyramidally coordinated and linked together via two μ2-coordinating oxygen atoms (Oi) and two chelating (–COOi) carboxyl­ate groups. The structure is completed by two monodentate carboxyl­ate groups (–COOo) attached to the outer tin atoms (Fig. 3[link]).

The central, planar and centrosymmetric four-membered (Sn–O)2 rings exhibit acute [75.90 (5)/75.78 (5)°] angles at tin and obtuse ones [104.10 (5)/104.22 (5)°] at oxygen. Its rhomboidal shape with different Sn—O distances results from the position of the μ3-oxygen atom (O1/O3) within the trigonal–bipyramidal coordination sphere of the inner tin atoms (Sn1/Sn3): bonds where the O atom is in an equatorial (eq) position are significantly shorter [2.042 (1)/2.046 (1) Å] than those where the O atom is in an axial (ax) position [2.164 (1)/2.152 (1) Å]. The second axially positioned Sn—O bond at the inner tin atoms is even longer [2.251 (1)/2.248 (1) Å] as it results from a coordinative bond of the oxygen atom (O11/O31) of the μ2-benzoate ligand (–COOi). In contrast to the prediction of the VSEPR concept, the bond angle between both equatorially positioned n-butyl groups is widened to 146.20 (7)/141.73 (7)°.

The conformation of the outer, six-membered Sn–O–C rings is defined by an angle of 19.9 (1)/23.4 (1)° between the O–C–O plane and the Sn–O–Sn plane (Fig. 4[link]). In case of the trigonal–bipyramidally coordinated outer tin atoms, Sn—O bond lengths follow the rule: d(Sno—Oμ3)eq [2.027 (1)/2.022 (1) Å] < d(Sno—Oμ1-carb)ax [2.175 (1)/2.188 (1) Å] < d(Sno—Oμ2-carb)ax [2.260 (1)/2.235 (1) Å]. Bond angles between the n-butyl groups at the tin atoms are 142.49 (7) and 135.64 (7)°.

The different coordination modes of both benzoate ligands are reflected in different C—O bond lengths: in the case of the monodentate carboxyl­ate group (–COOo), the C—O bonds are of different strengths: the short, strong one [1.232 (2)/1.222 (3) Å] indicates a localized C=O double bond whereas the long, weak one [1.307 (2)/1.306 (3) Å] of the Sn-coordinating oxygen atom indicates a localized C—O single bond. In the case of the bridging benzoate groups (–COOi) both C—O bonds are of almost equal lengths [1.259 (2),1.258 (2)], in accordance with a delocalized π-system. In the two benzoate ligands, the carboxyl­ate groups and the phenyl groups are not co-planar, but are inclined to each other at angles of 15.1 (2), 14.8 (3)/3.9 (3) and 17.3 (1)°.

Another characteristic feature of the mol­ecular structure comprises some additional, very weak inter­actions [d(Sn⋯O) = 2.7857 (2)/2.7141 (2) Å] of the μ1-O atoms (O21/O41) of the outer carboxyl­ate groups with the inner tin atoms (Sn1/Sn3), while those of the μ0-O atoms (O22/O42) of the outer carboxyl­ate groups with the outer tin atoms (Sn2/Sn4) are still longer [2.8901 (2)/2.9883 (2) Å]. Taking these weak inter­actions into account, both kinds of Sn atoms adopt a strongly distorted octa­hedral coordination. All bonding features (except the last ones) of the two mol­ecules are summarized in Fig. 5[link], which also visualizes the major structural differences between the mol­ecules as a result of the different orientations of the n-butyl groups relative to the Sn–O framework.

3. Supra­molecular features

Inter­molecular inter­actions are restricted to van der Waals and C—H⋯O contacts. Among the latter, a very short [d(H⋯O) = 2.487 Å], nearly linear [〈(C—H⋯O) = 172.6°] contact between the hydrogen atom H26 of a phenyl ring of mol­ecule 1 and the non-coordinating oxygen atom O42 of the second mol­ecule attracts attention as it leads to a chain-like arrangement of the two mol­ecules along [111] (Fig. 6[link]). All other C—H⋯O=C contacts are longer than 2.73 Å.

4. Database survey

Tetraorganodistannoxane di­carboxyl­ates, [R2Sn(OOCR′)]2O, have been extensively structurally characterized. The Cambridge Structural Database (Groom et al., 2016[Groom, C. R., Bruno, I. J., Lightfoot, M. P. & Ward, S. C. (2016). Acta Cryst. B72, 171-179.]) quotes as many as 214 entries (date: 10.01.2017). The majority of organic moieties attached to tin are found to be n-butyl (145) while for the di­carboxyl­ates benzoic acid derivatives (90) are the most studied. Even for the combination of R = nBu and R′ = benzoic acid derivatives not less than 67 structures are described, but from the parent compound with R′ = PhCOO, only the structure of the methyl compound (R = Me) has been completely characterized (Amini et al., 2002[Amini, M. M., Abadi, S. H., Mirzaee, M., Lügger, T., Hahn, F. E. & Ng, S. W. (2002). Acta Cryst. E58, m697-m699.]).

5. Synthesis and crystallization

[{nBu2Sn(OOCPh)}2O]2 was obtained from an equimolar mixture of 0.300 g (1.2 mmol) of n-di­butyl­tin oxide with 0.147 g (1.2 mmol) of benzoic acid in ethanol under reflux for 3.5 h. After removal of the solvent, single crystals were obtained by recrystallization of the solid from ethanol/n-hexane.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. Most of the hydrogen atoms were clearly identified in difference Fourier syntheses. Their positions were calculated assuming idealized geometries and allowed to ride on the carbon atoms with C—H = 0.98 Å (–CH3), 0.99 Å (–CH2–), and 0.95 Å (C—Harom) using one common isotropic displacement parameter for each n-butyl and phenyl group. Disorder of both n-butyl groups at the outer Sn atom (Sn4) of the second mol­ecule was refined using a split model with site occupancies of 0.806 (3)/0.194 (3) and 0.702 (3)/0.298 (3). In order for the structural model to be chemically meaningful, the atomic positions of the minor components were restrained to a target value for the C—C distance [d(C—C) = 1.526 (3) Å] and displacement parameters were taken from the chemically equivalent C atoms of the major occupancy component.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
