Abstract:
A salen-based macrocycle possessing adamantane units was constructed from two ethylenediamine and two disubstituted adamantane-bearing salicylaldehyde components. The addition of methanol to a tetrahydrofuran solution of the macrocycle afforded the crystals via hollow spherical and fused aggregates, and X-ray crystallographic analysis showed that the macrocycle had a rhomboidal structure. The use of chloroform instead of methanol gave the crystals of a square-shaped macrocycle without the formation of self-assembled materials.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
