A solvent‐free agostically propagated polymeric variant of a previously reported hydride‐containing inverse crown molecule has been prepared, namely tetra‐μ 2 ‐diisopropylamido‐di‐μ 2 ‐hydrido‐dimagnesium(II)disodium(I), [Mg 2 Na 2 H 2 (C 6 H 14 N) 4 ]. The asymmetric unit contains two crystallographically independent centrosymmetric molecules, each existing as a cationic eight‐membered ring, with alternating metal and N atoms, which acts as a host towards two hydride anions. The metal amide rings are linked via Na⋯C agostic interactions to produce one‐dimensional polymeric chains propagating along the crystallographic b direction.
