    Notes: The fullerides [M(NH3)6]C60 (M = Mn2+, Cd2+) have been synthesized by ion exchange in liquid ammonia and analyzed by X-ray single-crystal diffraction. With both complex cations the C602- 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.

    Description / Table of Contents: Electrocrystallization of FulleridesThe fullerides P(C6H5)4C60 · P(C6H5)4Cl, P(C6H5)4C60 · P(C6H5)4Br und As(C6H5)4C60 · As(C6H5)4Cl have been prepared by electrocrystallization. Single crystal structure determinations have shown them to be isostructural in space group I4/m with lattice constants a = 12.5731(9), c = 20.142(3) Å; a = 12.5378(10), c = 20.606(5) Å; a = 12.6003(11), c = 20.377(4) Å, respectively. Spectroscopic and magnetic investigations prove the existence of a C60- anion, showing orientational disorder in all three fullerides.
    Notes: Die Fulleride P(C6H5)4C60 · P(C6H5)4Cl, P(C6H5)4C60 · P(C6H5)4Br und As(C6H5)4C60 · As(C6H5)4Cl wurden durch Elektrokristallisation erhalten. Die Strukturbestimmung an Einkristallen ergab, daß alle drei Verbindungen isotyp in der Raumgruppe I4/m mit den folgenden Gitterkonstanten kristallisieren: a = 12,5731(9), c = 20,142(3) Å; a = 12,5378(10), c = 20,606(5) Å; a = 12,6003(11), c = 20,377(4) Å (Die Zahlen beziehen sich auf die Fulleride in der oben angegebenen Reihenfolge). Spektroskopische und magnetische Untersuchungen belegen die Existenz eines C60--Anions, das im Kristall orientierungsfehlgeordnet vorliegt.
