Inorganic Chemistry Basics

Ligand preference and possible coordination geometries of the metal center are important bioinorganic principles. Metal ligand preference is closely related to the hard-soft acid-base nature of metals and their preferred ligands. These are listed in Table 1.7.  

It is possible to modify a hard nitrogen ligand toward an intermediate softness by increasing the polarizability of its substituents or the n electron cloud

In order to systematize the procedures and basic premises of quantum mechanics, a set of postulates has been developed that provides the usual starting point for studying the topic. Most books on quantum mechanics give a precise set of rules and interpretations, some of which are not necessary for the study of inorganic chemistry at this level. In this section, we will present the postulates of quantum mechanics and provide some interpretation of them, but for complete coverage of this topic the reader should consult a quantum mechanics text such as those listed in the references at the end of this chapter. 

The colour of the transition metal ions, which is one of their major characteristics, arises directly from the interaction between the outer orbital electrons of the transition metal and the electric field created by the presence of the co-ordinating ligands. The theory of this is called ligand field theory, and is well covered in most basic textbooks on inorganic chemistry (e.g., Cotton and Wilkinson, 1976). Ligand field theory is an extremely powerful tool, which... 

Unfortunately (or better, fortunately) chemical innovation is very fast and any matter rapidly ages. Per speed vely, the dynamic aspects of inorganic compounds (or, molecular machinery ) will become more and more sophisticated (their interpretation thus requiring also more and more sophisticated electrochemical techniques), but the basic equipment to their operation will remain in some ways still valid for a long time (screws, bolts, screwdrivers, pliers and drills are still basic pieces of the actual super-technological assemblies). In this picture, it is expected that the basic approach outlined here, to face with the electrochemical aspects of a number of topics in inorganic chemistry, will (hopefully) maintain its middle-term validity. 

So what is chemistry Obviously, chemistry is the study of chemicals or materials. It turns out, however, that there are two basic types of chemistry, one known as inorganic chemistry and the other as organic chemistry.
