Key indicators: single-crystal X-ray study; T = 295 K; mean (C-C) = 0.012 Å; R factor = 0.048; wR factor = 0.136; data-to-parameter ratio = 17.9.In the title compound, [Sn(C 6 H 11 ) 3 (C 7 H 3 Br 2 O 3 )], the Sn atom is four-coordinate and possesses a distorted Sn(C 3 O) tetrahedral geometry, with Sn-C bond lengths in the range 2.132 (6)-2.144 (6) Å and with Sn-O = 2.086 (4) Å . The uncoordinated carboxylate O atom forms a weak contact with the Sn atom, with an SnÁ Á ÁO separation of 2.962 (2) Å . Related literature
