Popis:	Transparent single crystals of a new iodate Cs5[Sc2(IO3)9](IO3)2 were synthesized under mild hydrothermal conditions. X-ray diffraction of single crystal was used to determine the large crystal structure with 52 independent atoms, sp. gr. P21/c. The building blocks [Sc(IO3)6]3− of Sc octahedra and six (IO3) groups are condensed into a framework; the structure contains additional isolated (IO3) groups. Large Cs cations occupy holes and form an intercrossing framework. Similar building blocks [M(IO3)6] are known for many iodates; however, most are isolated. Their topology and symmetry differ and determine the properties of the compounds.
