Interstratified structures are a common phenomenon in layered silicates and the differentiation between random and ordered interstratifications might be in some cases difficult. Atypical basal spacings observed for Ni-exchanged fluorohectorites could be related to such an ordered interstratified structure. Applying powder X-ray diffraction, thermal gravimetric analysis, and various spectroscopic techniques, an ordered interstratification of smectite-like [Ni(H2O)(6)](2+) and condensed, chlorite-like [Ni(OH)(2-y)(H2O)(y)](x)(y+)interlayers, where x refers to the degree of condensation, was observed. By simple ion exchange a corrensite-like structure was obtained with a structural formula of {[Ni(OH)(0.83)(H2O)(1.17)](0.37)(1.17+)}(Int). (1){[Ni(H2O)(6)](0.28)(2+)}(Int). (2)[Mg5Li] Si-8 > O20F4. Improving the contrast between the two distinct d-spacings and between the electron densities of the interlayers by partial ion exchange with a long chain alkylammonium cation or thermal annealing, helped to increase the intensity of superstructure reflections rendering the ordered interstratified structures more clearly visible.
