A Bi(Ⅲ) contained heteropolymate compound Na3H2[Ce3(H2O)18Bi2W22O76] 23H2O 1 has been synthesized. It crystallizes in the triclinic system, space group P1 with a = 14.370(3), b = 17.113(3), c = 24.764(5) , = 74.33(3), = 77.20(3), ?= 65.29(3)u001f, V = 5285.3(18) 3, Z = 2, Mr = 6908.66, Dc = 4.341 g/cm3, F(000) = 6042, m(MoKa) = 28.543 mm-1, R = 0.0604 and wR = 0.1659 for 15788 reflections with I > 2(I). The structure analysis revealed that in the anionic framework of the title compound the [Bi2W22O76]14- anions are connected by Ce3+ and Na+ cations into a three dimensional network. It crystallizes in the triclinic system, space group P1 with a = 14.370 (3), b = 17.113 (3), c = 24.764 V = 5285.3 (18) 3, Z = 2, Mr = 6908.66, Dc = 4.341 g / cm3, F (5) = 74.33 (3) = 77.20 (3) 000) = 6042, m (MoKa) = 28.543 mm-1, R = 0.0604 and wR = 0.1659 for 15788 reflections with I> 2 (I). The structure analysis revealed that in the anionic framework of the title compound the [Bi2W22O76] 14- anions are connected by Ce3 + and Na + cations into a three dimensional network.
