Supramolecular confinement of C-60, S-8, P4Se3 and toluene by metal(II) macrocyclic complexes

Treatment of S-8 or P4Se3 with {5,7,12,14-tetramethyldibenzo[b,i]-1,4,8,11- tetraaza[14]annulenato}metal(II) [= M(TMTAA)] in carbon disulfide afforded the solid state 1 : 2 inclusion complexes [(S-8){M(TMTAA)}(2)], M = Ni or C u (isostructural), or [(P4Se3){Ni(TMTAA)}(2)]. A toluene inclusion complex [(MeC6H5)Ni(TMTAA)] resulted from the recrystallisation of [Ni(TMTAA)] from toluene. Recrystallisation of [Ni(TMTAA)] from CS2-hexane resulted in the unsolvated complex. All complexes are comprised of interlocking dimers of t he macrocycle, and in the inclusion complexes these dimers act as homotopic divergent receptors either through the methyl- or phenyl-lined surfaces. S olid state 1 : 1 C-60 inclusion complexes of [M(TMTAA)], M = Cu or Zn, have individual macrocycle molecules acting as heterotopic divergent receptors.
