N2 - The crystal structure of Rb2B4O7 is described, the first structure determined for anhydrous rubidium borates. It belongs to the triclinic system, sp. gr. P1; a = 9.860(4), b = 10.653(6), c = 6.649(4) Å; α = 103.4(1), β = 101.4(1), γ = 89.1(1)°; V = 665.5 Å3; Z = 4; dcalc = 3.26 g/cm3. The atomic coordinates of atoms of the isostructural K2B4O7 compound were used in the anisothropic approximation, R=0.053. The structure consists of a three-dimensional skeleton formed by three kinds of mixed anions: [BIIIO1.5]0 triangles; [BIV2 BIIIO5.5]2- simple rings consisting of two tetrahedra and a triangle; and [BIV2 BIII2 O7]2- double rings formed by [BIV2 BIIIO5.5]2- simple rings of two shared tetrahedra.
