Post‐metallation derivatives of the sodium dialkyl(amido)zincate reagent (TMEDA)Na(μ‐TMP)Zn( t Bu)2 (TMEDA is N,N,N′,N′‐tetramethylethylenediamine and TMP is 2,2,6,6‐tetramethylpiperidide) have been of structural interest due to the insight they give into aromatic metallation mechanisms. Here, the aromatic substrate is formally replaced with [ZnO]2 to give tetra‐tert‐butyldi‐μ4‐oxido‐bis(tetramethylethylenediamine‐κ2 N,N′)bis(μ2‐2,2,6,6‐tetramethylpiperidin‐1‐ido‐κ2 N:N)disodiumtetrazinc hexane 0.59‐solvate, [Na2Zn4(C4H9)4(C9H18N)2O2(C6H16N2)2]·0.59C6H14. The crystallographically centrosymmetric complex retains many of the structural features of its parent monomer but has an unusual dimeric structure, with a central planar Zn–O–Zn–O ring joined to two orthogonal near‐planar Zn–O–Na–N rings through the distorted tetrahedral geometries of the oxide ions.
