Monoaquatris(tetraoxorhenate (VII)) bismuth(III), Bi(Re0(4))3(H(2)0) was prepared by reaction of (BiO)2C0(3)/Bi2(C0(3))3 with concentrated HRe0(4) at room temperature. The pale yellow compound crystallize triclinic in the space group PI;, (No. 2); with two formula units per unit cell (a = 746.0(1) pm, b = 111. 1(2) pm, c = 990.5(2) pm, a = 100.99(3)°, p = 99.88(3)°, y = 100.17(3)° ). The main feature of the crystal structure is a distorted bicapped trigonal prism of Bi[(Re0(4))3;2 (Re0(4))2/2 (Re0(4))2/2 (H(2)0)], which are connected each other through [ReOJ-tetrahedra to form a three-dimensional network. In the titled compound, the cation Bi3+ is eightfold coordinated which agree with the tendency observed in other compounds of the family
