Sumario: | The asymmetric unit of the title compound, 2C(18)H(15)Te(+)·2Br(−)·C(3)H(6)O or Ph(3)TeBr·0.5Me(2)CO, contains two crystallographically independent triphenyltelluronium cations, two bromide anions, and one disordered [site-occupancy ratio = 0.581 (7):0.419 (7)] solvent molecule. Interionic Te⋯Br interactions connect the cations and anions into a tetrameric step-like structure. The primary coordination spheres of both Te atoms are TeC(3) trigonal pyramids: three short secondary tellurium–bromine interactions expand the coordination geometry of one of the Te atoms to an octahedron. While the other Te atom shows only two Te⋯Br secondary bonding interactions, it is also six-coordinated due to a Te⋯π interaction [3.769 (2) Å] with one of the phenyl rings of the adjacent cation. |
