Abstract

C₁₆H₁₂Cl₄Te, (1), M_r = 473.66, P2₁/c, a = 8.3919(9), b = 14.474(1), c = 14.585(1) Å, β = 94.057(9)°, Z = 4, R₁ = 0.0378. C₁₆H₁₂Br₄Te, (2), M_r = 651.50, Pnma, a = 19.159(2), b = 16.787(1), c = 5.781(1) Å, Z = 4, R₁ = 0.0437. In both compounds the primary geometry about the Te^IV atom is a pseudo-trigonal-bipyramidal arrangement, with two halide atoms in apical positions, and the lone pair of electrons and C atoms in the equatorial plane. The Te^IV atoms are involved in secondary interactions resulting in the self-assembly of a chain-like supramolecular array in (1) and into a three dimensional supramolecular array in (2). Compound (1) has a Z configuration with the chlorine atom and the tellurium moiety bonded at the same side in adjacent atoms. In (2) the bromine atom and the dibromotellurium moiety are bonded at adjacent carbons in a cis fashion.
