Tetramine Aspect Ratio and Flexibility Determine Framework Symmetry for Zn₈ L₆ Self-Assembled Structures.

ABSTRACT: We derive design principles for the assembly of rectangular tetramines into Zn₈ L₆ pseudo-cubic coordination cages. Because of the rectangular, as opposed to square, geometry of the ligand panels, and the possibility of either Δ or Λ handedness of each metal center at the eight corners of the pseudo-cube, many different cage diastereomers are possible. Each of the six tetra-aniline subcomponents investigated in this work assembled with zinc(II) and 2-formylpyridine in acetonitrile into a single Zn₈ L₆ pseudo-cube diastereomer, however. Each product corresponded to one of four diastereomeric configurations, with T, T_h , S₆ or D₃ symmetry. The preferred diastereomer for a given tetra-aniline subcomponent was shown t
