• Structural Examination of Halogen-Bonded Co-Crystals of Tritopic Acceptors
  作者：Stefan Andree、Abhijeet Sinha、Christer Aakeröy

  DOI：10.3390/molecules23010163

  日期：——

  A series of tritopic N-heterocyclic compounds containing electrostatically and geometrically equivalent binding sites were synthesized and subjected to systematic co-crystallizations with selected perfluoroiodoarenes in order to map out their structural landscapes. More than 70% of the attempted reactions produced a co-crystal as indicated by IR spectroscopy. Four new crystal structures are reported and in all of them, at least one potential binding site on the acceptor is left vacant. The absence of halogen bonds to all sites can be ascribed primarily due to deactivation of the σ-hole on the iodo-arene donors and partially due to steric hindrance. The tritopic acceptors containing 5,6-dimethylbenzimidazole derivatives yield discrete tetrameric aggregates in the solid state, whereas the pyrazole and imidazole analogues assemble into halogen-bonded 1-D chains.

• Self-Assembly of Ball-Shaped Molecular Complexes in Water

  日期：2002.5.1

  We present a simple and versatile access to spheroidal molecular assemblies with pronounced stability in highly polar solvents. These complexes are composed of doubly and triply charged complementary building blocks based on ammonium or amidinium cations and phosphonate anions. Their high thermodynamic stability is best explained by the formation of a cyclic array of alternating positive and negative charges interconnected by a regular network of hydrogen bonds. Association constants reach 10(6) M-1 in methanol and often surpass 10(3) M-1 in water. The broad range of binding energies correlates well with the varying degree of preorganization of both complex partners. As a byproduct of these investigations, new recognition motifs for histidine and arginine esters and the unsubstituted guanidinium ion are proposed. The additional introduction of methyl groups in the 2-, 4-, and 6-positions of the central benzene ring in either cations or anions causes a marked drop in the corresponding K-a values of 1 order of magnitude; the related rotational barriers were estimated at 0.3-2.1 kcal/mol. Spontaneous formation of defined 2:1 complexes from three components has also been observed.
