Bis(μ-chloroacetato-κ²O:O′)bis(chloro­acetato-κO)di-μ₃-oxido-tetrakis[dibenzyl­tin(IV)]

The title tetra­nuclear complex mol­ecule, [Sn₄(C₇H₇)₈(C₂H₂ClO₂)₄O₂], has crystallographically imposed inversion symmetry. Each Sn atom has a distorted trigonal–bipyramidal geometry, with the equatorial plane formed by an oxido O atom and two C atoms of two benzyl anions. The configuration of the complex is stabilized by a pair of C—H...O hydrogen bonds. In the crystal, complex mol­ecules are linked into zigzag chains along [110] by C—H...O hydrogen bonds.

S1. Comment

Organotin derivatives of carboxylic acid ligands have been extensively studied due to their biological activities (Gielen et al., 1988). In our ongoing studies on chloroacetic acid and organotin, the title compound has been synthesized and we report herein its crystal structure.

The molecular structure of the tetranuclear title compound is shown in Fig. 1. Each Sn atom is five-coordinated by two carboxylic O atoms, an oxo O atom, and two C atoms of two benzyl anions into a distorted trigonal-bipyramidal geometry very similar to that observed in a related compound (Teoh et al., 2002). The Sn—O distances are in the range 2.024 (2)–2.217 (2) Å. The conformation of the complex molecule is stabilized by a pair of C—H···O hydrogen bonds (Table 1). In the crystal (Fig. 2), complex molecules are connected along the [110] direction forming zigzag chains by C—H···O hydrogen bonds.

S2. Experimental

The reaction was carried out under nitrogen atmosphere. Chloroacetic acid (4 mmol) was added to a mixture of ethanol and benzene (1:3 v/v, 30 ml) with sodium ethoxide (4 mmol). The mixture was stirred for 0.5 h and then dichlorodibenzyltin (4 mmol) was added and the mixture was stirred at room temperature for 12 h. Crystals suitable for X-ray analysis were obtained by slow evaporation of a dichloromethane–petroleum ether (1:2 v/v) solution over a period of two weeks. Analysis, calculated for [(C₆H₅CH₂)₈(C₂H₂ClO₂)₄O₂Sn₄] (Mr = 1609.71): C 47.75, H 4.00%; found: C 47.82, H 3.95%.

S3. Refinement

All H atoms were positioned geometrically and refined as riding on their parent atoms, with C—H = 0.93–0.97 Å, and with U_iso(H) = 1.2 U_eq(C).
