(Received 15 November 2008; accepted 3 December 2008; online 10 December 2008)

In the title compound, [Sn(CH3)3(C7H2Cl3O2)]n, the tin(IV) atom exhibits a slightly distorted trigonal-bipyramidal geometry with two O atoms of symmetry-related carboxyl­ate groups in the axial positions and three methyl groups in the equatorial positions. In the crystal structure, the metal atoms are linked by carboxyl­ate bridges into polymeric chains extending along the b axis.

Comment top

Organoantin(IV) derivatives have recently attracted considerable attention due to the significant antimicrobial properties (Wang et al., 2007). As a part of our ongoing investigations in this field, we have synthesized the title compound and present its crystal structure here.

In the title compound (Fig. 1), the Sn—O bond distances (Table 1) are comparable to those found in related organotin carboxylates (Ma et al., 2006). The Sn atom assumes a slightly distorted trigonal-bipyramidal coordination geometry, provided by two O atoms of symmetry related carboxylate groups at the axial positions and three methyl groups at the equatorial positions. In the crystal structure, the metal atoms are linked by carboxylate bridges into polymeric chains extending along the b axis (Fig. 2).

Experimental top

The reaction was carried out under nitrogen atmosphere. 2,4,6-Trichlorobenzoic acid (1 mmol) and sodium ethoxide (1.2 mmol) were added to a stirred solution of benzene (30 ml) in a Schlenk flask and stirred for 0.5 h. Trimethyltin chloride (1 mmol) was then added and the reaction mixture was stirred for 12 h at room temperature. The resulting clear solution was evaporated under vacuum. Colourless crystals suitable for X-ray analysis were obtained by slow evaporation of a dichloromethane/methanol (1:1 v/v) solution (yield 83%. m. p. 403K). Anal. Calcd (%) for C10H11Cl3O2Sn: C, 30.94; H, 2.86; O, 8.24; Sn, 30.58; Found (%): C, 30.89; H, 2.90; O, 8.31; Sn, 30.62.

Refinement top

H atoms were positioned geometrically, with methyl C—H distances of 0.96 Å and aromatic C—H distances of 0.93 Å, and refined as riding on their parent atoms, with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(C) for the methyl groups.
