Abstract The Lewis acidity of tin in a diorganotin dicarboxylate is demonstrated in this first example of a 1/1 adduct of the ester with a neutral ligand. The structure of dibutyltin bisphenylacetate hydrate [(C4H9)2Sn(O2CCH2C6H5)2·H2O] has been determined from 1211 ∥F 0∥≥6σ∥F c ∥ MoKα reflections and refined to anR F of 0.061 [space groupP2/a witha=8.416(2),b=10.391(5),c=14.28(1) Å,β=98.42(4)° andZ=2]. TheC α atoms [Sn-C 2.101(8) Å; C-Sn-C 169.9(5)°] make up the apices and the Ocarboxylate [Sn-O 2.234(5), 2.439(7) Å; O-Sn-O 55.7(2)°] and Owater [Sn-O 2.342(8) Å] atoms the equatorial points of thetrans-C2SnO5 pentagonal bipyramid around the Sn atom. The molecular symmetry isC 2, and the Sn and Owater atoms lie along a crystallographic twofold axis. The aqua ligand forms donor H-bonds with neighboring carboxylato groups to link the molecules into a double zigzag chain running parallel toa.
