Antiferromagnetic Alkali Metal Oxohydroxoferrates(III) with Correlated Hydrogen Bonding Systems.

ABSTRACT: The oxohydroxoferrates(III) A ₂[Fe₂O₃(OH)₂] (A=K, Rb, Cs) were synthesized under hydroflux conditions. Approximately equimolar mixtures of the alkali metal hydroxides and water were reacted with Fe(NO₃)₃ ⋅ 9H₂O at about 200 °C. The product formation depends on the hydroxide concentration, therefore also other reaction products, such as KFeO₂, K_2-x[Fe₄O_7-x(OH)_x] or α-Fe₂O₃, are obtained. The crystal structures of the oxohydroxoferrates(III) A ₂[Fe₂O₃(OH)₂] follow the same structural principle, yet differ in their layer stacking or/and their hydrogen bonding systems dep
