(5-Bromosalicylato)triphenyltin(IV)

The title compound, [Sn(C₆H₅)₃(C₇H₄BrO₃)], crystallizes with two independent molecules in the asymmetric unit, the molecular conformations of which are almost identical. In each molecule, the Sn atom is coordinated by one O and three C atoms in a distorted tetrahedral geometry [Sn—O = 2.045 (4) and 2.087 (4) Å; Sn—C = 2.082 (7)–2.117 (7)Å]. The hydroxy groups are involved in intramolecular O—H

O hydrogen bonds.

Comment top

Organotin esters of carboxylic acids are widely used as biocides, as fungicides and in industry as homogeneous catalysts. We have therefore synthesized the title compound, (I), and present its crystal structure here.

In (I) (Fig. 1), the tin atoms are four-coordinated by the three C atoms from phenyls and the oxygen atom of the monodentate carboxyl group. Thus, the geometry of the tin centers displays a distorted tetrahedral coordinated sphere with six angles ranging from 95.2 (2) ° to 125.0 (3) °. The Sn1—O1 distance of 2.045 (4) Å is close to the reported values for triorganotin carboxylates (Ma et al., 2006).

A series of new triorganotin(IV) pyridinedicarboxylates has been synthesized by the reaction of trimethyltin(IV), triphenyltin(IV) or tribenzyltin(IV) chloride with 2,6(3,5 or 2,5)-H₂pdc (pdc = pyridinedicarboxylate), see: Ma et al. (2006).

Experimental top

The reaction was carried out under nitrogen atmosphere. 5-Bromosalicylic acid (1 mmol) and sodium ethoxide (1.2 mmol) were added to the solution of benzene in a Schlenk flask and stirred for 0.5 h. Triphenyltin 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. 427 K). Analysis, calculated (%) for C₂₅H₁₉BrO₃Sn (Mr = 566.00): C, 53.05; H, 3.39. found: C, 53.36; H, 3.23.
