A double-layered hydroxide, 3CaO.Al 2 O 3 .CaI 2 .10H 2 O

Abstract : The structure of 3CaO.Al2O3.CaI2.10H2O, also formulated as Ca2Al(OH)6I.2H2O, consists of positively charged main layers, [Ca2Al(OH)6]+, and negatively charged interlayers, [I-,2H2O]. The oxygen coordination numbers of the Al3+ and Ca2+ cations are six and seven, respectively, and all non-H atoms occupy ordered sites.
