title: Self-Assembly of Two Chiral Supramolecules with Three-Dimensional Porous Host Frameworks: (Delta){[Fe(II)(phen)(3)][Fe(III)Na(C(2)O(4))(3)]}(n)() and Its Enantiomer.
abstract: Two chiral supramolecules with enantiomeric three-dimensional porous host frameworks, (Delta){[Fe(II)(phen)(3)][Fe(III)Na(C(2)O(4))(3)]}(n) (1) and (Lambda){[Fe(II)(phen)(3)][Fe(III)Na(C(2)O(4))(3)]}(n) (2) (phen = 1,10-phenanthroline), have been synthesized, and their crystal structures have been determined. The structural analysis shows that compounds 1 and 2 are a pair of enantiomers, both consisting of a three-dimensional porous skeleton formed by (Delta)/(Lambda){[Fe(III)Na(C(2)O(4))(3)](2-)}(n) and guest (Delta)/(Lambda)[Fe(phen)(3)](2+) units. The circular dichroism spectrum measurements confirmed the optical activity and the enantiomeric nature of complexes 1 and 2.
