Synthesis and molecular structure of seven isomers of C70(C2F5)10

A mixture of C₇₀(C₂F₅)_n (n = 8, 10, 12) compounds was synthesised by a reaction of C₇₀ with C₂F₅I at 350 °C followed by HPLC separation; crystal structure determination for seven isomers of C₇₀(C₂F₅)₁₀ revealed a large variety of addition patterns most of which are unprecedented in the regiochemistry of [70]fullerene.
