Extract

Dark blue-green Fe(II)Fe(III) hydroxychlorides and -sulphates were described by Feitknecht & Keller (1950) and later by Bernal et al. (1959). To further understand the formation and transformation of these compounds, Taylor & McKenzie (1980) and Taylor (1980) prepared Fe(II)Al(III) and Fe(II)Fe(III) hydroxychlorides, -sulphates and -carbonates by a more controlled hydrolysis reaction. These compounds, referred to as ‘green rusts’ by Bernal et al. (1959), are isostructural with hydrotalcite. However, the X-ray diffraction patterns can vary with the M(II)/M(III) cation ratio as it departs from the ideal value of 3, and with the interlayer anion.
