KLiSiF6 and CsLiSiF6 were synthesized via a high-pressure/high-temperature synthesis route. Even though, both substances crystallize in the orthorhombic crystal system with space group Pbcn (no. 60), they show different crystal structures. Main motifs of KLiSiF6 are an [SiF6]2? and an [LiF6]5? unit. In contrast, the main motifs of CsLiSiF6 are an [SiF6]2? and an [LiF5]4? entity. Within both substances, these units are interconnected and form 3-dimensional networks. The substances were characterized via single-crystal and powder X-ray diffraction, as well as infrared spectroscopy and EDX measurements. Additionally, Mn4+-doped KLiSiF6 was analyzed by means of luminescence spectroscopy. It displays line emission in the red spectral region. The maximum emission wavelength is λmax=631 nm.
