| Abstract;Two types of three-dimensional supramolecular complexes are formed by reversible self-assembly of trimeric zinc(II) complexes (Zn3L) with trianionic trithiocyanuric acid (TCA3-) in aqueous solution at neutral pH. The first is a supramolecular cage, which is formed by 4:4 complexation of Zn3L with TCA3-, is represented by a cuboctahedron, having an inner cavity depicted as a twisted truncated tetrahedron. It was discovered that the supramolecular cage is capable of encapsulating organic guest molecules such as adamantane and tetrapropylammonium cation. On the other hand, 3:3 assembly of linear Zn3L with TCA3- yields the second supramolecular complex, whose structure is represented as a trigonal prism. (author abst.) |
