Poly[tetra­butyl­tetra­kis­(μ₂-hydrogen phenyl­phospho­nato)ditin(IV)]

In the title compound, [Sn₂(C₄H₉)₄(C₆H₆PO₃)₄]_n, the basic unit is a dimer containing two symmetry-related Sn^IV atoms bridged by two hydrogenphenylphosphonate anions. This fragment is located about an inversion center, and each Sn^IV atom is linked to two other hydrogenphenylphosphonate anions, giving a layered structure parallel to (010). The coordination geometry for the Sn^IV atoms is close to octa­hedral. The layers are connected via O—H...O hydrogen bonds, generating a three-dimensional network. One butyl group is disordered over two sets of sites, with occupancies of 0.49 (2) and 0.51 (2).

S1. Comment

The interest to synthesize new organotin derivatives is related to their various applications in different fields: agrochemicals, surface disinfectants and marine antifouling paints, etc. (Evans & Karpel, 1985); thus many groups have been involved in the search for new organotin compounds (Holmes et al., 1988; Hadjikakou & Hadjiliadis, 2009). Our group has yet published some papers dealing with SnBu_2, SnMe₃ and SnPh₃-residues containing derivatives (Diassé-Sarr et al., 1997; Sall et al., 1992; Boye & Diassé-Sarr, 2007). In continuation of this work, we have initiated here the study of the interactions between PhPO₃H₂ and SnBu₂Cl₂ which yielded Sn₂Bu₄(PhPO₃H)₄ . The phosphorous acids are very important in in vivo systems. Phosphorous acids are known for their biocidal activities, as some organotin compounds (Molloy et al., 1981). Combining them seems worthy for having specific derivations allowing a positive combination of that property. This explains our focus on that type of compounds.

The asymmetric unit of the title compound contains two dibutyltin(IV) units and four hydrogen phenylphosphonates, leading to [SnBu₂(PhPO₃H)₂]₂ formula (Fig. 1). The structure consists to two equivalents Sn1 atoms bridged by two hydrogenophenylphosphonates, generating a dimer. This fragment is located on a inversion center. Each Sn1 atom is linked to two others dimers based on Sn2 atoms, via other bridging hydrogenophenylphosphonates (P2, P3, P4), generating a 2D polymer. Hydrogen bonds O—H···O involving the P—OH groups of the hydrogenophenylphosphonates give a 3D crystal structure (fig. 2).

The hydrogen bonds lead to almost equal P—O bond distances [P1—O1: 1.513 (3) Å, P1—O2: 1.516 (3) Å, different of the P—OH bond: P1—O3: 1.563 (3) Å], as reported for dicyclohexylammonium trimethylbis(hydrogen phenylphosphonato)-stannate(IV) (Diop et al., 2011). The geometry around the P atom is a distorted tetrahedron [O1—P1—O2: 113.49 (18)°, O1—P1—C23: 109.6 (2)°]. The sum of the O—Sn—O angles is 360.13° for Sn1 and the C1—Sn1—C5 angle value of 174.37 (18)° indicates some deviation from ideal trans octahedral arrangement around the Sn^IV ions.

S2. Experimental

The title compound has been synthesized by allowing PhPO₃H₂ (0.2 g) to react with SnBu₂Cl₂ (0.1 g) in ethanol (1/1 ratio). The mixture was stirred for two hours and submitted to a slow solvent evaporation at room temperature, giving, after some days, regular colorless crystals suitable for X-ray work (m.p. 463 K).

S3. Refinement

One butyl group was found to be disordered: atoms C14, C15 and C16 are disordered with C14A, C15A, C16A, and occupancy factors converged to 0.49 (2) and 0.51 (2), respectively. Hydroxyl H atoms (H3, H6, H9 and H12) were found in a difference map and refined freely, although with restrained bond lengths. Other H atoms were placed in idealized positions and refined as riding to their carrier C atoms, with C—H = 0.95 (aromatic CH), 0.98 (methyl CH₃) or 0.99 Å (methylene CH₂ groups). Isotropic displacement parameters for H atoms were calculated as U_iso(H) = xU_eq(carrier atom); x = 1.2 or 1.5.
