Acetonyldichloro[(Z)-2-chloro-2-phenylvinyl]tellurium(IV), helical chains of metal complexes.

The primary geometry about the Te(IV) atom in the title compound, [TeCl2(C8H6Cl)(C3H5O)] or C11H11Cl3OTe, is a pseudo-trigonal-bipyramidal arrangement, with two Cl atoms in apical positions, and the lone pair of electrons and C atoms in the equatorial plane. The Te(IV) atom is involved in three secondary interactions, two intramolecular [Te...O = 2.842 (3) A and Te.Cl3 = 3.209 (1) A] and one intermolecular [Te...Cl = 3.637 (1) A], the latter giving rise to a helical chain. These helices are linked by C-H...O interchain interactions.
