Popis: The preparation and structure of the layered complex formed by the intercalation reaction of FeOCl with propargylamine are reported. The solid isolated from this reaction is a crystalline material with a magnetic susceptibility at room temperature of 0.9 × 10 -2 emu g -1 , and μ eff 18 BM. Reaction of this complex by heating under argon by exposure to moist air, or by washing with water results in new materials with larger susceptibilities, 1.8 × 10 -2 emu g -1 , and μ eff 72 BM, but with a more disordered structure as determined by X-ray powder diffraction and scanning electron microscopy. The preparation of the butylamine intercalate of FeOCl under identical conditions gave only the literature-reported product. The formation of a fine-particle green rust (I) and not the hydrolysis product γ-FeOOH from the propargylamine complex of FeOCl is suggested based upon magnetic susceptibility. Mossbauer spectroscopy. FTIR, and X-ray powder diffraction evidence. A model to account for the difference in the reactivity and properties of the butylamine and propargylamine complexes of FeOCl is proposed.
