The atomic structure of Pb5(Ge1-xSix)O11, (x = 0.0, 0.30, 0.42) single crystals was investigated at 150 and 295 Ê using X-ray structure analysis. The structure of all the crystals at 150 Ê correspond to spase group P3. Isomorphous substitution of Ge by Si in these solid solutions is not statistical: Ge positions in GeO4 tetrahedra contain more Si ions than those in Gå2Î7 group.
