The obtained parameters are presented in Table 1. The result demonstrates that the a parameter was influenced by the cation ionic radii Zn2+ (0.74 Å) > Mg2+ (0.72 Å) > Ni2+ (0.69 Å) (Shannon 1976). Meanwhile, the lattice c parameter depends mostly on the size and intercalation amount of interlayer anions and on the charge density to a lesser degree. Furthermore, the important value of interlayer distance in Zn-Al LDHs may indicate the formation of an anionic bilayer.
