ORTEP-type diagram of the X-ray (single crystal) structure of 14-(OTf)2. Only one of the two independent molecules shown, with protons omitted for clarity. (A) Top view of 142+ showing the 12-membered macrocycle. (B) Side view of the full molecule illustrating the bridging (I–O–S–O-I) η2-triflate ligands and the overall “paddle-wheel” geometry. (C) Comparison of divergence in the hypothetical C–I σ* vectors in cyclic bis-iodonium dications.
