Abstract:
From fluorination of [60]fullerene with MnF3/K2NiF6 at 480 degrees C we have isolated and characterized by both 19F NMR spectrum and single crystal X-ray analysis, a C1 isomer of C60F36; it has three planar delocalized aromatic rings, three short C=C bonds (due to compression from the adjacent fluorines), the longest FC-CF bond (1.684 A) yet found in a fluorofullerene, and its stability is predicted by calculations.
