摘要：
Reaction of di-n-butyltin oxide with 2-amino-5-chlorobenzoic acid in 1:2 stoichiometry yields the title compound which crystallizes as the six-coordinate diorganotin dicarboxylate monomer. The crystal structure of the compound reveals the tin atom situated on a crystallographic two-fold axis in a skew-trapezoidal bipyramid geometry. The trapezoidal plane is defined by two asymmetrically chelating carboxylate groups; Sn-O bonds are 2.123(4) and 2.484(5) Angstrom and the C-Sn-C angle is 141.7(6)degrees: The nitrogen atom of the amino group of the carboxylate ligand does not participate in any significant interactions with the tin atom.
