New cocrystallines are reported that contain C-60 with anti-formed macrocyclic metal complexes of octaethylporphyrin (OEP). From the results of the electronic structure obtained using a DV-X alpha molecular orbital calculation, the configuration of the OEP in a cocrystalline of C-60 with Ag(II)(OEP) or Ni(II)(OEP) is predicted to be the anti-formed structure. It is shown that the anti-formed configuration of the OEPs can be confirmed in Ag(II)(OEP).C-60. 2C(6)H(6) and 2Ni(II)(OEP).C-60. 2C(6)H(5)Cl according to a structural prediction we have made by means of electronic structure calculations using the DV-X alpha method. It is also revealed that the C-60 is located at the closest approach to the centered atom involving the 5:6 carbon ring junction in these cocrystallines. Using the DV-X alpha method, it is predicted that new types of pi -d material can be produced. The material should have high conductivity and a significant magnetic moment via the pi -d interaction in the charge transfer salt of [Cr(III)(Por)](+)[C-60](-). (C) 2001 Elsevier Science B.V.
