| Abstract: | Abstract We report here the first layer rigidity study which has been performed on layer double hydroxides (LDH's) having a fixed-host layer. The LDH materials studied have the chemical formula (CO3)0.195(1?x)Cl0.39x]:Zn0.61Al0.39(OH)2], 0≤x≤1. An inter-layer rigidity parameter of p=4.84±0.06 was determined for these compounds from a fit of the standard version of the discrete finite layer rigidity model to the composition-dependence of the normalized basal spacing measured using X-ray diffraction. This result validates the previous results obtained from the more complex, variable-host layer LDH materials. |
