Abstract The crystallographic structure of Ni(II)−Fe(III) hydroxy-chloride green rusts obtained by oxidation of a FexNi1−x(OH)2 precipitate is isomorphous with that of the ferrousferric green rust one and independent of the value of P=Fe/Ni. Mössbauer spectra exhibit two quadrupole doublets after further oxidation of the compounds which correspond to a formula (3-x)Ni(OH)2 · xFeOOH · Fe(OH)2Cl. The Fe3+ ions are found to occupy preferentially the sites close to the Cl− ions and the Ni2+ those far from them. However the ordering of the Fe3+ ions is not perfect.
