Intramolecular and intermolecular bromine⋯polyfluoroarene interactions: The crystal structure of bis{κC-1-(2,3,5,6-tetrafluoropyridyl)-3-benzylimidazolin-2-ylidene}tetrabromodimercury

In the crystal structure of bis{kC-1-(2,3,5,6-tetrafluoro-pyridyl)-3-benzylimidazolin-2-ylidene}tetrabromodimercury each terminal bromine atom is involved in an intramolecular and an intermolecular lp-π interaction with tetrafluoropyridyl rings. The interactions are orthogonal to one another and the HgBr bond.
