Abstract
The compound has tetragonal symmetry, space group I4m2 with: a=b=6.315(2) and c = 15.000(2) Å and contains 6 formula units. Diffraction data with 0 < 2θ < 50° (MoKα radiation) were collected on a Nonius CAD‐4 automatic diffractometer within the octant hkl. The structure was solved by Patterson synthesis and refined by full‐matrix least squares to a final R(F) of 4.9% for 159 independent reflections with I > 3σ(I). The structure consists of a stacking of gallium triangular‐faced dodecahedra linked to each others through direct and bifurcated GaGa bonds in a non‐compact netting leaving room for a sublattice of rubidium atoms with shortened RbRb distances.Keywords
