(Received 21 May 2009; accepted 16 June 2009; online 20 June 2009)

The title compound, [Sn(C₆H₅)₃(C₁₇H₂₅O₃S)]_n, comprises two symmetry-independent five-coordinated triphenyltin molecules which are linked by carboxylate bridges into a polymeric chain. The Sn^IV atom is in a distorted trans-C₃SnO₂ trigonal-bipyramidal geometry. The presence of two bulky tert-butyl groups on the benzene ring prevents any hydrogen-bonding interactions involving the hydroxyl substituents.

Comment top

Organotin carboxylates have received much attention due to their extensive applications in different fields of science, including biological activity (Yehye et al., 2009). Triorganotin carboxylates are either monomeric or polymeric, depending on the steric bulk of the organic substituents. In the case of polymeric structures, the asymmetric triorganotin fragments are linked by strong carboxylate bridges (Tiekink, 1991; Parvez et al. 2002; Zhang et al., 2007).

The structure of the title compound, (I), contains two symmetry unrelated triphenyltin units which form a polymeric chain by strong carboxylate bridges. The tin atom in the polymeric unit adopts the trigonal bipyramidal geometry in which the axial positions are occupied by the carboxylate-O atoms of the adjacent 2-(3,5-di-tert-4-hydroxybenzyl)sulfanylacetate ligands. The Sn—O bond distances of 2.186 (2) Å, 2.452 (2) Å and 2.151 (2) Å, 2.384 (2) Å are in good agreement with values reported for many polymeric triorganotin carboxylates (Tiekink, 1991).

Experimental top

Compound (I) was prepared by refluxing 2-(3,5-di-tert-4-hydroxybenzyl)sulfanylacetic acid (0.39 g, 1 mmol) with triphenyltin hydroxide (0.37 g, 1 mmol) in absolute ethanol for 2 h. Colourless crystals were obtained by slow evaporation at room temperature.

Special details top

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

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
