Abstract Scope |
Relative to framework structures, which must conform to the topological requirements imposed by ionic or covalent bonding, a greater range of crystal packing arrangements is possible in molecular compounds, due to the less restrictive nature of their cohesive forces. A large number of three-dimensional molecular motifs is available for crystal packing to form molecular crystals, which however must satisfy the underlying thermodynamic requirements for chemical stability. Since porosity is closely related to crystal packing, there are extended possibilities for formation of molecular structures with technologically significant porosity. In this study we examine the crystal packing and porosity in relatively simple molecular co-crystals based on pristine C60 fullerene in combination with other molecules having various dimensional attributes. |
