The fullerides [M(NH 3 ) 6 ]C 60 (M = Mn 2+ , Cd 2+ ) have been synthesized by ion exchange in liquid ammonia and analyzed by X‐ray single‐crystal diffraction. With both complex cations the C 60 2– units are in fixed orientations, and their geometries have been determined with good accuracy. An inspection of the fulleride dianions with respect to geometric deformations in the title compounds and three further independent determinations has led to the conclusion that no significant static Jahn‐Teller distortion is present.
