title: catena-Poly[sodium-μ2-(N,N,N',N'-tetra-methyl-ethane-1,2-diamine)-κ(2) N:N'-sodium-bis-[μ2-bis-(trimethyl-sil-yl)aza-nido-κ(2) N:N]].
abstract: The title compound, [Na2(C6H18NSi2)2(C6H16N2)] n , was found to consist of dimeric [Na(NSiMe3)2] units with crystallographically imposed centrosymmetry based upon four-membered NaNNaN rings. The dimers are bridged by N,N,N',N'-tetra-methyl-ethylenediamine ligands, which act in an unusual extended non-chelating coordination mode. This gives a one-dimensional coordination polymer that extends parallel to the a-axis direction.
