Ligand inorganic complexes

Inorganic complexes confaining organic ligands exhibif af leasf some vibrations which are characteristic of fhe ligands. 

Each entry has the % of total metal present as the free hydrated ion, then the ligands forming complexes, in decreasing order of expected concentration. For instance, in inorganic freshwater at pH 9, Ag is present as the free aquo ion (65%), chloro-complexes (25%), and carbonato-complexes (9%).

This effect is observed, for example, in inorganic complexes, where the metal ion is octahedral and the six ligands might be expected to occupy positions at equal distances at the corners of an octahedron, in an ideal structure. In the actual structure however, the octahedron may be distorted with four ligands in a square planar coordination and the remaining two ligands at opposite corners at longer distances. Many oxides exhibit Jahn-Teller distortions. 

One way to calculate the ZFS parameters is through ligand field theory (52,53) but for quantitative calculations it is nowadays possible to use accurate correlated ab initio methods. It is known that the direct spin—spin contribution (SSC) is dominant for organic molecules, and for a long time it was assumed that for inorganic complexes exclusively the SOC dominates. Nevertheless, exceptions to this rule have been identified (54,55). 

The nomenclature for describing optically active inorganic complexes and ligand conformations requires some discussion. Formerly, active...
