Crystal structure of 2-phenyl-2λ(4),3-ditellura-tetra-cyclo-[5.5.2.0(4,13).0(10,14)]tetra-deca-1(12),4,6,10,13-pentaen-2-ylium tri-fluoro-methane-sulfonate.

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.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt).
