Solid state synthesis of coordination compounds from basic metal salts

Abstract

The preparation of the complex salts [H₂im]₂[MCl₄] (H₂im = imidazolium, M = Co, 1; Zn, 2; Cu, 3) and coordination compounds [MCl₂(Him)₂] (M = Co, 4; Zn, 5; Cu, 6) by a range of solid-state and solid-gas reactions is reported. Compounds 4–6 and the related [{MCl₂(4,4′-bipy)}_n] (M = Co, 7; Zn, 8) were prepared by the solid state reactions of metal hydroxide or carbonate salts (or their equivalent) with the hydrochloride salt of the appropriate ligand (imidazole or 4,4′-bipy).
