Th(BrO₃)₃·H₂O single crystals were grown from its aqueous solution at room temperature. Single crystal XRD, Raman and FTIR techniques were used to investigate the crystal structure. The crystal structure was solved by Patterson method. The as grown crystals are in monoclinic system with space group P21/c. The unit cell parameters are a = 12.8555(18) ?, b = 7.8970(11) ?, c = 9.0716(10)?, α = 90°, β = 131.568° and γ = 90° and unit cell volume is 689.1(2)?³. Z = 8, R factor is 5.9. The Raman and FTIR studies indicate the lowering of symetry of bromate anion from C_3V to C₁. Hydrogen bonds with varying strengths are present in the crystal. The centrosymmetric space group P21/c of the crystal is confirmed by the non-coincidence of majority of Raman and IR bands.
