In the title polymeric coordination compound, [Sn(CH3)3(C8H6ClO2)]n, the Sn atoms exhibit a distorted trigonal-bipyramidal geometry with the carboxyl­ate O atoms of the 2-chloro­phenyl­acetato ligands in axial positions and with the equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 2-chloro­phenyl­acetato ligand, forming a chain structure.

Comment top

The chemistry of organotin(IV) derivatives is a subject of study with growing interest due to their significant antimicrobial properties as well as antitumor activities (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. The title compound, which is shown in Fig.1 forms an extended one-dimensional chain structure arising from Sn—O bridges formed by the 2-(2-chlorophenyl)acetato ligands. The Sn—O bond distances in the compound (Sn(1)—O(1) = 2.396 (5) Å; Sn(1)—O(3) = 2.194 (4) Å) 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 and three methyl groups in the equatorial positions and two O atoms of symmetry related carboxylate groups in the axial positions.

Experimental top

The reaction was carried out under a nitrogen atmosphere. 2-(2-chlorophenyl)acetic 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 to the reactor and the reaction mixture was stirred for 12 h at room temperature. The resulting clear solution was evaporated under vacuum. The product was crystallized from a solution of dichloromethane/methanol (1:1) to yield colourless blocks of the title compound (yield 81%. m.p.390 K). Anal. Calcd (%) for C11H15Cl1O2Sn1 (Mr = 333.37): C,39.63; H, 4.54; Cl, 10.63. Found (%): C, 39.51; H, 4.64; Cl, 10.75.

Refinement top

The 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, O) or 1.5 Ueq(C) for the methyl groups.
