Share this page:. Crabtree Edited Books 1. Inorganic chemistry deals with the synthesis and behavior of inorganic and organometallic compounds. This field covers all chemical compounds except the myriad organic compounds carbon-based compounds, usually containing C-H bonds , which are the subjects of organic chemistry.

The distinction between the two disciplines is far from absolute, as there is much overlap in the subdiscipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis , materials science , pigments , surfactants , coatings , medications , fuels , and agriculture. Many inorganic compounds are ionic compounds , consisting of cations and anions joined by ionic bonding.
In any salt, the proportions of the ions are such that the electric charges cancel out, so that the bulk compound is electrically neutral. The ions are described by their oxidation state and their ease of formation can be inferred from the ionization potential for cations or from the electron affinity anions of the parent elements. Important classes of inorganic compounds are the oxides , the carbonates , the sulfates , and the halides.
Many inorganic compounds are characterized by high melting points. Inorganic salts typically are poor conductors in the solid state. Other important features include their high melting point and ease of crystallization. Where some salts e. The simplest inorganic reaction is double displacement when in mixing of two salts the ions are swapped without a change in oxidation state. In redox reactions one reactant, the oxidant , lowers its oxidation state and another reactant, the reductant , has its oxidation state increased.
The net result is an exchange of electrons. Electron exchange can occur indirectly as well, e. When one reactant contains hydrogen atoms, a reaction can take place by exchanging protons in acid-base chemistry. In a more general definition, any chemical species capable of binding to electron pairs is called a Lewis acid ; conversely any molecule that tends to donate an electron pair is referred to as a Lewis base.
As a refinement of acid-base interactions, the HSAB theory takes into account polarizability and size of ions. Inorganic compounds are found in nature as minerals. Soil may contain iron sulfide as pyrite or calcium sulfate as gypsum. Inorganic compounds are also found multitasking as biomolecules : as electrolytes sodium chloride , in energy storage ATP or in construction the polyphosphate backbone in DNA. The first important man-made inorganic compound was ammonium nitrate for soil fertilization through the Haber process. Inorganic compounds are synthesized for use as catalysts such as vanadium V oxide and titanium III chloride , or as reagents in organic chemistry such as lithium aluminium hydride.
Subdivisions of inorganic chemistry are organometallic chemistry , cluster chemistry and bioinorganic chemistry. These fields are active areas of research in inorganic chemistry, aimed toward new catalysts , superconductors , and therapies. Inorganic chemistry is a highly practical area of science.

The manufacturing of fertilizers is another practical application of industrial inorganic chemistry. Descriptive inorganic chemistry focuses on the classification of compounds based on their properties. Partly the classification focuses on the position in the periodic table of the heaviest element the element with the highest atomic weight in the compound, partly by grouping compounds by their structural similarities. When studying inorganic compounds, one often encounters parts of the different classes of inorganic chemistry an organometallic compound is characterized by its coordination chemistry, and may show interesting solid state properties.

In modern coordination compounds almost all organic and inorganic compounds can be used as ligands. The "metal" usually is a metal from the groups , as well as the trans - lanthanides and trans - actinides , but from a certain perspective, all chemical compounds can be described as coordination complexes. A topical theme within this specialization is supramolecular coordination chemistry. Due to their often similar reactivity, the elements in group 3 Sc , Y , and La and group 12 Zn , Cd , and Hg are also generally included, and the lanthanides and actinides are sometimes included as well.
Main group compounds have been known since the beginnings of chemistry, e. Experiments on oxygen, O 2 , by Lavoisier and Priestley not only identified an important diatomic gas, but opened the way for describing compounds and reactions according to stoichiometric ratios. The discovery of a practical synthesis of ammonia using iron catalysts by Carl Bosch and Fritz Haber in the early s deeply impacted mankind, demonstrating the significance of inorganic chemical synthesis.
Main group compounds also occur in nature, e. Compounds containing metals from group 4 to 11 are considered transition metal compounds.
Compounds with a metal from group 3 or 12 are sometimes also incorporated into this group, but also often classified as main group compounds. Transition metal compounds show a rich coordination chemistry, varying from tetrahedral for titanium e. A range of transition metals can be found in biologically important compounds, such as iron in hemoglobin.

Usually, organometallic compounds are considered to contain the M-C-H group. Operationally, the definition of an organometallic compound is more relaxed to include also highly lipophilic complexes such as metal carbonyls and even metal alkoxides. Organometallic compounds are mainly considered a special category because organic ligands are often sensitive to hydrolysis or oxidation, necessitating that organometallic chemistry employs more specialized preparative methods than was traditional in Werner-type complexes.
Synthetic methodology, especially the ability to manipulate complexes in solvents of low coordinating power, enabled the exploration of very weakly coordinating ligands such as hydrocarbons, H 2 , and N 2. Because the ligands are petrochemicals in some sense, the area of organometallic chemistry has greatly benefited from its relevance to industry.
