Butyldichloro(phenylethynyl)tellurium(IV)

In the title compound, [TeCl2(C4H9)(C8H5)] (C12H14Cl2Te), the intramolecula r geometry around the Te-IV is pseudo-trigonal bipyramidal, with the Cl ato ms in the apical positions and the Te lone pair occupying the fifth positio n in the equatorial plane. Taking into account the intermolecular secondary Te ... Cl1 contact of 3.266(1) Angstrom, trans to the Te-C-vinyl, the stru cture may be regarded as pseudo-octahedral. distances and angles are: Te-Cl 2.486(1) and 2.551(1), Te-C 2.020(3) and 2.146(3) Angstrom; Cl-Te-Cl 173.8 1(3), Cl-Te-C 89.94(10), 86.59(9), 87.84(10) and 87.98(9), and C-Te-C 97.66 (13)degrees. All of the C atoms lie in a plane, with the Te atom displaced 0.2220(2) Angstrom from the plane in the direction of Cl2.
