Inorganic compounds ligand complexes

Since many inorganic compounds and complexes contain groups or atoms dealt with previously, the earlier chapters of this book should also be studied for any relevant information. For example, the chapters on silicon, boron, phosphorus and polymers contain a great deal of information relevant to inorganic compounds. Also, if interest is in, say, metal-olefin compounds, then sections dealing with alkenes should be examined, not only because the band positions of the free ligand should be known but also because some bands for these complexes may also be included in these sections. 

In empirical formulas of inorganic compounds, electropositive elements are listed first [3]. The stoichiometry of the element symbols is indicated at the lower right-hand side by index numbers. If necessary, the charges of ions are placed at the top right-hand side next to the element symbol (e.g., S "). In ions of complexes, the central atom is specified before the ligands are listed in alphabetical order, the complex ion is set in square brackets (e.g., Na2[Sn(OH)+]). 

It is often difficult to represent inorganic compounds with the usual structure models because these structures are based on complex crystals space groups), aggregates, or metal lattices. Therefore, these compounds are represented by individual polyhedral coordination of the ligands such as the octahedron or tetrahedron Figure 2-124d).

Class A Type MX, . (Note We generally assume that the ligand is monovalent.) A small number of almost purely covalent inorganic compounds that are extracted by nonsolvating organic solvents. As these complexes are nonelectrolytes and almost as inert as the solutes of Type 1-A, they are treated jointly in section 4.4. 

The vast majority of metal complexes in the solid state are insulators and do not exhibit any interesting electrical conduction properties because the metal atoms are surrounded by insulating ligands which prevent the passage of carriers from one site to another. This review will be limited to a discussion of the electrical conduction properties of coordination compounds, and will not include simple inorganic compounds with high electrical conductivity such as mixed metal oxides, (3-alumina and TaSe3.
