Are these organo-metallic compounds? My understanding says organo-metallic = organic + metallic compunds. 

One already known to me is Grignard Reagent ($\ce{RMgX}$). 

But would you consider $\ce{NaOMe}$ or $\ce{NaCCH}$ as an organometallic compound? Would you consider $\ce{LiOAc}$, $\ce{LiOMe}$, $\ce{LiN(Me)2}$ or $\ce{LiMe}$?
To my understanding, only $\ce{NaC#CH}$ and $\ce{LiCH3}$ are organometallic compounds.

According to the IUPAC definition of organometallic compounds, these must contain


  at least one metal-carbon bond between an organic molecule, ion, or radical and a metal.
