The “break‐and‐seal” approach was applied to synthesize the new fulleride [K(DB24C8)(DME)] 2 C 60 · DME by reacting fullerene C 60 with potassium and dibenzo‐24‐crown‐8 (DB24C8) in dimethoxyethane (DME). Single crystals were grown from solution by the modified “temperature difference method”, single‐crystal X‐ray analysis was performed revealing the structure [ C 2/ c , Z = 4, a = 31.133(4), b = 15.127(2), c = 21.433(3) Å, β = 117.506(3)°, R 1 = 0.056, wR (all) = 0.171, 8459 independent reflections]. Due to crystal symmetry, the C 60 2– anion is disordered between two well distinguishable orientations. The distribution of the bond lengths within the fullerene is discussed and attributed to a Jahn–Teller distortion.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
