Dichloro[(E)-2-chloro-1-vinyl-cyclohexanol](4-methoxy phenyl)Te(IV). A case of conformational polymorphism

C₁₅Cl₃H₁₉O₂Te, M_r = 465.25, (1), P2₁/a, a = 9.8303(9), b = 17.492(2), c = 10.911(1) Å, β = 108.521(8)°, Z = 4, R₁ = 0.0274. (2), P2₁/c, a = 8.2661(9), b = 22.863(2), c = 9.828(1) Å, β = 108.894(8)°, Z = 4, R₁ = 0.0379. In both compounds, the primary geometry of the Te^IV atom is a pseudo-trigonal-bipyramidal arrangement with two halide atoms in apical positions and a lone pair of electrons and C atoms in the equatorial plane. In (1), the Te^IV atom is involved in an intermolecular secondary interaction resulting in the self-assembly of a chain-like supramolecular array. In (2), molecules are linked in centrosymmetric dimers through Cl…H–O interactions.
