The pentavalent bismuthate BaBi 2 O 6 was prepared by a low‐temperature hydrothermal reaction using NaBiO 3 .nH 2 O and Ba(OH) 2 .8H 2 O as starting materials. The X‐ray powder diffraction pattern was indexed with a hexagonal cell (space group: P‐31 m), the same as a PbSb 2 O 6 ‐type crystal. The crystal structure of this compound was refined using synchrotron X‐ray powder diffraction data. The cell parameters were found to be a =5.57534(6) and c =5.7381(1) Å and the final reliability (R) factors obtained by Rietveld analysis were R wp =5.15 % and R p =3.62 %. This compound exhibited profound photocatalytic activity for phenol decomposition under visible light irradiation.
