摘要
First ionic multi-component complex CoTPP.2C(60)(CN)(2).2Bz(2)Cr.3C(6)H(4)Cl(2) (COTPP: cobalt(II)tetraphenylporphyrin; Bz(2)Cr: bis(benzene)chromium; C6H4Cl2: o-dichlorobenzene) has been synthesized. CoTPP molecules and fullerides form channels providing the accommodation of Bz(2)Cr(.+) and C6H4Cl2. For the first time it is shown that, in contrast to the neutral fullerenes, the cobalt atom of CoTPP coordinates to the fullerene anions with short Co...C(fullerene) distance of 2.28 Angstrom. CoTPP-C-60(CN)(2)(-) anion is diamagnetic according to the EPR- and SQUID-measurements. The shape of the starting molecule retains at the formation of the C-60(CN)(2)(.-) anion-radicals. The length of Cequivalent toN bonds are 1.143 and 1.161 Angstrom. (C) 2002 Elsevier Science B.V. All rights reserved.
