Abstract δ-FeO(OH)-type solid solutions have been synthesized with compositions Fe1−x M x O1−x (OH)1+x ranging up tox=0.10 for M=Ca,x=0.35 for M=Mg or Cd andx=0.40 for M=Zn. The phases are characterized by X-ray diffraction and transmission electron microscope studies. A structural model giving satisfactory intensity agreement is postulated for Fe1−x Zn x O1−x (OH)1+x . In this model, Zn2+ ions are situated in the 0 0 0 octahedral sites of space group D 3d 3 -P¯3ml while the Fe3+ ions are almost equally distributed among both octahedral sites (0 0 0 and 0 0 1/2).
