metal-organic compounds
The title compound, [Cd(H2O)6]2(C24H2O16S8)·H2O, the bis[hexaaquacadmium(II)] salt of the p-sulfonatothiacalix[4]arene tetraanion, crystallizes as a hydrate; two symmetry-independent cations interact with the tetraanion via their coordinated water molecules. The Cd atoms and water O atom lie on special positions of site symmetry m and the complete calixarene anion is generated by mirror symmetry. The water molecule is weakly associated with the calixarene cavity by way of long O—HO hydrogen bonds.
