Abstract
AbstractThe “break‐and‐seal” approach was applied to synthesize the new fulleride [K(DB24C8)(DME)]2C60·DME by reacting fullerene C60 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 [C2/c, Z = 4, a = 31.133(4), b = 15.127(2), c = 21.433(3) Å, β = 117.506(3)°, R1 = 0.056, wR(all) = 0.171, 8459 independent reflections]. Due to crystal symmetry, the C602– 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)
