The double-layered hydroxide 3CaO·Al2O3·0.5CaBr2·0.5CaCl2·10H2O

J.-P. Rapin and M. François

Synopsis: The title compound is a double-layered hydroxide which belongs to the solid solution Ca2Al(OH)6BrxCl1-x·2H2O, where x can vary from 0 to 1. Chloride and bromide anions of the negatively charged interlayer [Br0.5Cl0.5·2H2O]- share statistically the same crystallographic site. Al3+ and Ca2+ cations are coordinated by six and seven O atoms, respectively. All water molecules are bonded to Ca2+ cations and assume the seventh coordination position.

Formula: Ca2Al(OH)6Br0.478Cl0.522·2H2O
