Pyrophoric organometallic compound solid

A large number of compounds exist between the branches of organic and inorganic chemistry that involve metals and metalloids bonding with organic compounds, including organometallics, soaps, and alkoxides. 

Organometallic compounds are compounds in which a metal is attached directly to a carbon atom in an organic molecule. The metal can be thought of as a substitute for a hydrogen atom. Almost all metals form organometallic compounds, thus their number renders it impossible to generalize about their properties and hazardous characteristics. They are used extensively as catalysts and as chemical reagents. Examples include  

Certain metalloids, like phosphorus and arsenic, when compounded with organic groups, are classed as organometallics. Organophosphorus compounds include four organic groups  

Organic compounds of arsenic syn. organoarsenic compounds are all toxic. They include phenyldichloroarsine, a tear gas and solvent. 

Metal alkyl and aryl oxyhydrides are similar to alkoxides in that they involve a metal hydride attached to the oxygen from an alkyl or aryl alcohol. Examples include the aluminium metal hydride sodium bis(2-methoxyethoxy) aluminohydride and lithium aluminium-tri-tert-butoxyhydride. They are dangerous fire risks in contact with water and can decompose to evolve hydrogen gas.
