On the basis of its ionic radius and known structural chemistry with oxygen donor ligands (Valkonen, 1979), scandium would be expected to have the hexahydrated ion in some of its compounds, for instance in the perchlorates and bromates. No structural data appear to be available, however, obviously because of the tendency of scandium compounds to undergo hydrolysis and the difficulty of forming good single crystals in aqueous solutions. Nevertheless, the hexahydrated R ion has been discovered recently in the solid hydrates of R perchlorates (R = La, Tb, Er) (Glaser and Johansson, 1981). For details of the structure, see table 35 and section 6.
