Abstract top

The title compound, [Sn(C4H9)3(C6H5O2S)]n, possesses an infinite chain structure. The SnO2C3 centre has a distorted trigonal-bipyramidal geometry ([tau] = 0.145) with the O atoms in the axial positions. Atoms of the thiophene group S1 and C4 are disordered over two sites The S atom and one C atom, with attached H atom, of the thiophene ring are disordered over two positions; the site occupancy factors are ca 0.7 and 0.3.

Comment top

The title compound, (I) (Fig. 1), possesses an infinite one-dimensional chain structure arising from Sn—O bridges to the ligand. The Sn1—O1 distances of 2.183 (6) Å and Sn1—O2A [symmetry code: -x + 2,y - 1/2,-z + 1/2] distance 2.482 (7) Å, are similar to those reported for other organotin carboxylates (Ma et al., 2006). The Sn atom has distorted trigonal-bipyramidal geometry[τ = 0.145; Addison et al.,, 1984], with atoms O1 and O2A in axial positions [O1—Sn1—O2A = 171.3 (2) °] and the C atoms of the three butyl groups in equatorial positions. The sum of the equatorial C—Sn—C angles is 358.6 °, indicating approximate coplanarity for these atoms.

Experimental top

The reaction was carried out under nitrogen atmosphere. 2-Thiopheneacetic acid (1 mmol) and sodium ethoxide (1.2 mmol) were added to the solution of benzene(30 ml) in a Schlenk flask and stirred for 0.5 h. Tri-n-butyltin chloride (1 mmol) was then added to the reactor and the reaction mixture was stirred for 12 h at 313 K. The resulting clear solution was evaporated under vacuum. The product was crystallized from a mixture of dichloromethane/methanol (1:1).(yield 80%; m.p. 457 K). Analysis calculated (%) for C18H32O2SSn (Mr = 431.19): C, 50.14; H, 7.48. found: C, 50.06; H, 7.53.

Refinement top

During the refinement atoms S1 and C4 were found to be disordered over two sites, and the ratio of the occupancy factors refined to 0.729 (11):0.271 (11) and 0.271 (11):0.729 (11) for atoms S1:S1'and atoms C4:C4', respectively. H atoms were positioned geometrically, with C—H = 0.93, 0.96 and 0.97 Å for aromatic, methyl and methylene H atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C) where x = 1.5 for methyl H and x = 1.2 for all other H atoms.
