Layered double hydroxides

Layered double hydroxides (LDH) are a class of ionic solids characterized by a layered structure with the generic layer sequence [AcB Z AcB]n, where c represents positively charged layers of metal cations, A and B are layers of hydroxide (OH−) anions, and Z are interlayers filled by various anions (ensuring the electroneutrality of the system) and neutral molecules such as water. Lateral offsets between the layers may result in longer repeating periods.
