Synthesis of Tetrahemispheraplexes with Ammonium, Alkylammonium or Alkaline Metal Ions as Exohedral Guests via Self‐Assembly or Guest Exchange

Supramolecular Coordination: Self-Assembly of Finite Two- and Three-Dimensional Ensembles

“…The ammonium counterions are hydrogen bonded to the oxygen donors at the triangular faces of the tetrahedron. 330 Temperature-dependent 1 H NMR studies showed the presence of homochiral, racemic complexes that were kinetically stable on the NMR timescale. Replacement of magnesium(II) by divalent transition metals allowed the syntheses of the corresponding tetranuclear complexes [(NH 4 ) 4 ∩{M 4 (L) 6 }] (M=Mn(II), Co(II), Ni(II), Zn(II)).…”

Rational Design of a Coordination Cage with a Trigonal‐Bipyramidal Shape Constructed from 33 Building Units

“…[1] The other class of supramolecular entities, discrete cage molecules, are conceived by rational design and prepared from a set of molecular building blocks that fit together such that the stoichiometry and symmetry elements of the product are predestined by the starting compounds. [2] In most of the coordination cages formed by this method the corners correspond to the metal centers, which are linked by twofold bridging ligands. [2][3][4][5][6] The use of building blocks that cover the faces of the cage is not as common.…”

“…Triangular subunits were used to form tetrahedral, octahedral, and adamantanoid coordination cages. [2][3][4][5][6] Cages with lower symmetry and triangular faces have been synthesized only in the past few years. [6][7][8][9][10] Here we report the rational design of a coordination cage with the outer shape of a trigonal bipyramid.…”

“…

In the printed article, [1] the stereo views of Figure 1 on page 824 and Figures 2 and 3 on page 826 have erroneously been expanded horizontally, thus causing difficulties in obtaining the intended 3D impression. Therefore, Figures 1Ϫ3 are reproduced here with the correct separation.
