Abstract: | In the title compound, Bi2B8O15, the Bi atom is coordinated to five or six O atoms. The B atoms exhibit two kinds of hybridization, sp2 and sp3, seen in the BO3 triangles and BO4 tetrahedra, respectively. Three BO3 triangles are connected to form a B3O6 planar ring. All atoms in the structure are connected together to form an infinite three‐dimensional network. |
