چکیده
In the title compound, C18H13Te2 (+)·CF3O3S(-), the Te(II) atom of the cation and one O atom of the tri-fluoro-methane-sulfonate counter-ion form a close-to-linear Te-Te-O system, with a Te-Te-O angle of 172.3 (1)° and a Te-O distance of 2.816 (5) Å, which may suggest the presence of a three-centre-four-electron (3c-4e) bond. Secondary Te⋯O inter-actions [3.003 (4) and 3.016 (4) Å], involving the second Te(II) atom of the binuclear mol-ecule, are also noted, resulting in a supra-molecular layer in the bc plane.
