title: A μ4-oxide-containing a dimeric variant of a sodium dialkyl(amido)zincate reagent.
abstract: 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-μ(4)-oxido-bis(tetramethylethylenediamine-κ(2)N,N')bis(μ(2)-2,2,6,6-tetramethylpiperidin-1-ido-κ(2)N:N)disodiumtetrazinc hexane 0.59-solvate, [Na(2)Zn(4)(C(4)H(9))(4)(C(9)H(18)N)(2)O(2)(C(6)H(16)N(2))(2)]·0.59C(6)H(14). 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.
