MUJICA, CARLOS et al. CRYSTAL STRUCTURE OF A NEW BISMUTH PERRHENATE Bi(Re04)3H20. J. Chil. Chem. Soc. [online]. 2008, vol.53, n.1, pp. 1364-1366. ISSN 0717-9707. http://dx.doi.org/10.4067/S0717-97072008000100008.
Monoaquatris(tetraoxorhenate (VII)) bismuth(III), Bi(Re04)3(H20) was prepared by reaction of (BiO)2C03/Bi2(C03)3 with concentrated HRe04 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[(Re04)3;2 (Re04)2/2 (Re04)2/2 (H20)], 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
