Abstract: In the structure of the title compound, [Y(H2O)9](BrO3)3, the yttrium(III) ion is surrounded by six equidistant water molecules forming a trigonal prism, which is capped by three more distant water molecules. The YIII ion lies on a special position (2c) with crystallographically imposed 
m2 symmetry. The title compound is isotypic with other [Ln(H2O)9](BrO3)3 (Ln = Pr, Sm, Tb and Yb) compounds, and the bromate anions are disordered in these structures. Relatively strong hydrogen bonds between the bromate anions and the water molecules stabilize the trigonal prism.
