The first sodiumâzinc and potassiumâzinc members
of the inverse crown ether family, an emerging class of heterometallic
macrocyclic amides previously limited to alkali metalâmagnesium
combinations, have been synthesised and crystallographically
characterised.
The synthesis and structural characterisation of the first sodium hydride complex stabilised by sterically demanding pyrazolate ligands are presented.
