Preparative methods 

For organometallic compounds the Preparative methods are very diverse but the following are normally useful.

• Reduction of metal salt in the existence of the ligand:

• Reaction of a transition metal salt along with a main-group organometallic compound. C₅H₅ is frequently delivered like the sodium salt Na⁺(C₅H₅)^-:

In other examples a Grignard reagent or aluminum alkyl may frequently be used:

• Metal vapor synthesis. Vaporizing the metal (example: through electron-beam heating) helps through giving the sublimation energy needed; metal atoms are then condensed in the existence of the ligand on the sides of the vessel, cooled with in liquid nitrogen. This technique is good for compounds that cannot be made through another route or ones stable only at low temperatures. For an instance,
