摘要

Single crystals of calcium bromide enneahydrate, CaBr2·9H2O, calcium iodide octahydrate, CaI2·8H2O, calcium iodide heptahydrate, CaI2·7H2O, and calcium iodide 6.5-hydrate, CaI2·6.5H2O, were grown from their aqueous solutions at and below room temperature according to the solid–liquid phase diagram. The crystal structure of CaI2·6.5H2O was redetermined. All four structures are built up from distorted Ca(H2O)8 antiprisms. The antiprisms of the iodide hydrate structures are connected either via trigonal-plane-sharing or edge-sharing, forming dimeric units. The antiprisms in calcium bromide enneahydrate are monomeric.
