                                    The title compounds of MM'SiF6 (M, M' = Li, Na, K, Rb, Cs) and Li0.5Na1.5SiF6 composition have been synthesized.  Their crystallographic, x-ray, and IR spectral properties were studied. The greatest distortion of the C3v symmetry of the hexafluorosilicate ion was observed in Li0.5Na1.5SiF6 crystal.
