Dibromo[(Z)-2-bromo-2-(hydroxymethyl)vinyl](n-butyl)tellurium(IV)

In the title compound, [TeBr₂(C₄H₉)(C₃H₄BrO)] or C₇H₁₃Br₃OTe, the primary geometry about the Te^IV atom is a pseudo-trigonal-bipyramidal arrangement with axial bromines and one equatorial position vacant. If an intermolecular, secondary Te...O bond of 3.041 (5) Å, 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) Å; Br–Te–Br 176.59 (3), Br–Te–C 88.87 (19), 89.0 (3), 89.65 (19) and 88.2 (3), C–Te–C 99.7 (3)°. The lattice is formed by hydrogen-bonded centrosymmetric dimers [O...Br = 3.399 (6) Å], which, in turn, are linked by the intermolecular secondary Te...O bond.
