Abstract:
The selective encapsulation behavior of cucurbit [5]uril and its lanthanide-capped molecular capsule toward nitrate and chloride ions has been investigated. Using fluorescence spectroscopy, the metal-free host has been demonstrated to selectively include nitrate ion. In contrast, the lanthanide-capped molecular capsule showed preference toward the inclusion of chloride ion. Solid-state structures of the nitrate and chloride inclusion complexes with the La(III)-capped molecular capsule have been crystallographically determined.

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...
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
