摘要：
Bismuth iodate was synthesized by precipitation from bismuth nitrate and iodic acid. The powder was dissolved in dilute nitric acid and single crystals were obtained by slow evaporation at 70degreesC. Bi(IO3)(3) crystallizes in the monoclinic system, space group P2(1)/n (Ndegrees 14), a = 8.8882(2) Angstrom, b = 5.9445(2) Angstrom, c = 15.2445(5) Angstrom, beta = 97.064(1) Angstrom. BiO9 polyhedra are edge-connected forming chains parallel to the b axis; these chains are linked through (IO3) groups forming layers parallel to (101). The 3D framework is designed by linking these layers through long I - O bonds. DSC analysis shows a remarkable thermal stability.
