'''二甲基铍'''是一种[[有机铍化合物]]，化学式 {{chem|Be(CH|3|)|2}}。

== 制备 ==
二甲基铍可以由[[格氏试剂]]（例如[[甲基碘化镁]]）和[[氯化铍]]在醚中反应而成。<ref name="DOI10.1107/S0365110X51001100" />
:<chem>BeCl2 + CH3MgI -> Be(CH3)2 + MgCl2 + MgI2</chem>
它也可以由[[二甲基汞]]和[[铍]]反应而成<ref name="DOI10.3891/acta.chem.scand.23-2921">{{Cite journal|title=On the Molecular Structure of Dimethylberyllium Monomer.|url=http://actachemscand.org/doi/10.3891/acta.chem.scand.23-2921|last=Almenningen|first=A.|last2=Haaland|first2=A.|date=1969|journal=Acta Chemica Scandinavica|doi=10.3891/acta.chem.scand.23-2921|volume=23|pages=2921–2922|language=en|issn=0904-213X|last3=Morgan|first3=G.
