Abstract:
In this tutorial review the wide-ranging use of metal ions in anion receptors is discussed with an emphasis on diversity and applications in sensing and soft materials. Metal-containing receptors are categorised according to the role of the metal as a structural unit, as a Lewis-acidic binding site or as part of a redox-active or luminescent reporter group. The differing chemistry of substitutionally inert metal complexes in anion hosts and metal-anion-ligand self-assembly processes is highlighted. The use of anion binding coordination polymer systems in anion separations and in supramolecular gels is also examined.

Properties of Organometallic Compounds
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...

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...
Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
