Description

Organometallic compounds by definition contain somewhere around one carbon metal covalent bond. There is a wide variety of these compounds; simple alkyl metal compounds like tetraethyllead, 2-alkene compounds like Zeise's salt, and 3-allyl compounds like allylpalladium chloride dimer are examples of major classes metallocenes containing cyclopentadienyl ligands and carbene complexes of transition metals. There are numerous metal carbonyls and metal cyanides, such as potassium ferricyanide and tetracarbonylnickel. Metal carbonyl and cyanide complexes without additional carbon ligands, according to some researchers, are not organometallic but rather pure inorganic. However, the majority of organometallic chemists consider metal complexes with any carbon ligand to be organometallic, including inorganic carbon. Metalorganic compounds are organic ligand containing metal complexes without a carbon metal covalent bond, such as metal carboxylates.

Organometallic chemistry is the study of chemical compounds that contain at least one chemical bond between a carbon atom of an organic molecule and a metal, such as alkali, alkaline earth, or transition metals, and sometimes broadened to include metalloids like silicon, boron, or selenium. In addition to bonds to organyl fragments or molecules, bonds to inorganic carbon, such as carbon monoxide metal carbonyls Even though, strictly speaking, they are not necessarily organometallic, discussions of related compounds like transition metal hydrides and metal phosphine complexes frequently include them. Metal containing compounds with organic ligands but no direct metal carbon bonds are referred to as metalorganic compounds, a term that is related but distinct. Metal phosphine complexes, metal diketonates, alkoxides, and dialkylamides. The field of organometallic science joins parts of customary inorganic and natural science. Other unusual bonding strategies are also known, despite the fact that it is known that carbon strongly favors the formation of four covalent bonds. Carboranes are exceptionally steady dodecahedral subsidiaries of the [B₁₂H₁₂]^2-unit, with one BH supplanted with a CH⁺. As a result, the carbon forms bonds with one hydrogen atom and five boron atoms. An octahedral carbon is bound to six phosphine gold fragments in the cation [(Ph₃PAu)₆C]²⁺. In nature, the iron molybdenum cofactor that is responsible for microbial nitrogen fixation also has an octahedral carbon center bonded to six iron atoms. This phenomenon has been attributed to the aurophilicity of the gold ligands, which provide additional stabilization of an otherwise labile species in accordance with prior hypothetical forecasts, the hexamethylbenzene dication contains a carbon iota with six bonds. More specifically, the formulation could be used to describe the dication structurally. This makes it an organic metallocene because a fragment is bonded to a fragment through all five of the ring's carbons.

All compounds that contain a bond between a metal atom and a carbon atom of an organyl group are considered to be organometallic compounds. In addition to the traditional metals, lanthanides, actinides, semimetals, and the elements boron, silicon, arsenic, and selenium are also considered to be organometallic compounds. Organometallic compounds like tetracarbonyl nickel and ferrocene are examples of transition metal containing compounds. Organolithium compounds like n-butyllithium, organozinc compounds like diethylzinc, organotin compounds like tributyltin hydride, organoborane compounds like triethylborane, and organoaluminium compounds like trimethylaluminium are additional examples of organometall. Methylcobalamin, a form of Vitamin, is a naturally occurring organometallic complex that has a cobalt methyl bond. The subfield of bioorganometallic chemistry frequently discusses this complex and other biologically relevant complexes. It is essential to keep in mind that each of the bonds to carbon.
