Description and Uses
Yttrium(III) sulfate octahydrate, with the chemical formula Y2(SO4)3-8H2O, consists of infinite layers parallel to (10\overline 1), with [Y(H2O)4(SO4)3/2] being the only repeating unit. The layers are connected to each other using only moderately strong hydrogen bonds. The trivalent yttrium cation is coordinated by eight O-atoms from four sulfate groups and four water molecules in a distorted square antitetrahedron [YO8]. It is of the same structural type as the rare earth sulfate octahydrate[1].
