Abstract
In the title compound, [TeBr2(C4H9)(C3H4BrO)] Or C7H13Br3OTe, the primary g eometry about the Te-IV atom is a pseudo-trigonal-bipyramidal arrangement w ith axial bromines and one equatorial position vacant. If an intermolecular secondary Te ... O bond of 3.041 (5) Angstrom, trans to the Te-C(vinylic) bond, is taken into consideration, the structure may be regarded as pseudo- octahedral. Distances and angles are: Te-Br 2.7295 (10) and 2.6115 (10), Te -C 2.092 (6) and 2.134 (7) Angstrom, Br-Te-Br 176.59 (3), Br-Te-C 88.87 (19 ), 89.0 (3), 89.65 (19) and 88.2 (3), and C-Te-C 99.7 (3)degrees. The latti ce is formed by hydrogen-bonded centrosymmetric dimers [O ... Br = 3.399 (6 ) Angstrom], which, in turn, are linked by the intermolecular secondary Te ... O bond.
