Interaction of Curved and Flat Molecular Surfaces. The Structures of Crystalline Compounds Composed of Fullerene (C60, C60O, C70, and C120O) and Metal Octaethylporphyrin Units

摘要: Solutions of C60, C60O, or C70 and metal complexes octaethylporphyrin (OEPH2) yield crystals that contain both the fullerene porphyrin. The structures C60·2CoII(OEP)·CHCl3, C60·2ZnII(OEP)·CHCl3, C60O·2CoII(OEP)·CHCl3 are isomorphous an ordered C60 cage surrounded by two MII(OEP) units. Although there is no covalent bond between porphyrin components, separation these units shorter than normal van der Waals contact. Crystals C70·CoII(OEP)·C6H6·CHCl3, C70·NiII(OEP)·C6H6·CHCl3, C70·CuII(OEP)·C6H6·CHCl3 also with fullerene, but have only one porphyrin/fullerene Crystalline C60·ClFeIII(OEP)·CHCl3 lacks close face-to-face porphyrin/porphyrin contact common to all other reported here retains intimate fullerene. In (C120O)·CoII(OEP)·0.6C6H6·0.4CHCl3 dimer enclosed CoII(OEP) moieties. Unfortunately disorder in th...
