(4,7,13,16,21,24-Hexaoxa-1,10-diaza-bicyclo-[8.8.8]hexa-cosa-ne)sodium perchlorate
Abstract:
The title compound, [Na(C(18)H(36)N(2)O(6))]ClO(4), was isolated and crystallized to understand more fully the ligand's binding specificity to cations. The cation and anion reside at an inter-section of crystallographic twofold and threefold axes. The carbon atoms in the cation are disordered over two positions in a 3:2 ratio, and the anion is equally disordered over two positions. The geometries of the cation and anion are typical. The compound packs in alternating sheets of discrete cations and anions stacked along the c axis, separated by a distance equal to one-sixth the length of the c axis.

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...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
