Structural characteristics of organometallic compounds

The structural characteristics of organometallic compounds are diverse and huge, but there are few constituent elements, such as C, H, O, N, P, S, X and so on. Organic compounds are isomeric.

Organic compounds formed by the direct connection of metal atoms and carbon atoms are called organometallic compounds, that is, compounds containing M-C bonds. Such as methyl potassium (CH3K), butyl lithium (C4H9Li), etc.

However, substances with O, S, N and other elements as metal coordination atoms in organic compounds are not organometallic compounds, but inorganic complexes, which belong to the research field of coordination chemistry.

Metal carbonyl compound (Mx(CO)y) with carbon monoxide as ligand is an inorganic complex, but it is closely related to other organometallic compounds and has similar properties, so it also belongs to organometallic compounds.
