organometallic compounds
An organometallic compound is a compound containing bonds from carbon atoms to metal (or metalloid) atoms. Organometallic compounds are thus at the crossroads of inorganic and organic chemistry.

There are three main types: (1) the alkyl derivatives of Group IA and IIA metals of the periodic table (including Grignard reagents), which have ionic bonds, and are powerful bases and reducing agents (see reduction); (2) derivatives of other main group metals, which are volatile, covalently-bonded compounds; and (3) transition metal derivatives (including sandwich compounds) with special d-orbital bonding.

Organometallic compounds are prepared by reacting a metal with an alkyl halide or a reactive hydrocarbon, or by substitution.
