Organometallic compound, any member of a category of substances containing at least one steel-to-carbon bond wherein the carbon is a part of an natural group. Organometallic compounds constitute a very massive institution of substances which have performed a first-rate function inside the improvement of the technological know-how of chemistry. They are used to a huge extent as catalysts (materials that boom the charge of reactions with out themselves being ate up) and as intermediates in the laboratory and in industry. The magnificence includes such compounds as ferrocene, a remarkably solid compound wherein an iron atom is sandwiched among hydrocarbon rings. Organometallic compounds are commonly discussed in phrases of the metallic as either principal-organization compounds or transition metallic compounds. The important-institution metals of organometallic compounds are generally considered to be the ones of the S-block and the heavier elements of the p-block (agencies 13–15) in the periodic desk of factors. The transition metals encompass those factors within the d- and f-blocks .

The physical and chemical houses of organometallic compounds vary greatly. Most are solids, specially the ones whose hydrocarbon organizations are ring-formed or fragrant, however a few are beverages and some are gases. Their warmness and oxidation balance vary broadly. Some are very solid, however a number of compounds of electropositive elements including lithium, sodium, and aluminum are spontaneously flammable. Many organometallic compounds are surprisingly toxic, specially those which can be volatile.
