Needle-like Cs₂Mo₇O₂₂ (7×1×1 mm³) and plated Cs₂Mo₅O₁₆ (4×3×2 mm³) crystals were obtained by spontaneous crystallization method from Cs₂Mo₅O₁₆ + 2%Cs₂O and Cs₂Mo₇O₂₂ + 2%Cs₂O melts. Peritectic nature of Cs₂Mo₅O₁₆ and Cs₂Mo₇O₂₂ compounds was confirmed by differential scanning calorimetry and thermogravimetric analysis. Cs₂Mo₅O₁₆ and Cs₂Mo₇O₂₂ crystal structures were constructed based on X-ray diffraction data. Unit cell parameters of Cs₂Mo₅O₁₆ and Cs₂Mo₇O₂₂ crystal samples were measured in 0–450 °C temperature range and thermal expansion vectors were calculated. Photoluminescence was registered on both Cs₂Mo₅O₁₆ and Cs₂Mo₇O₂₂ samples at 80 K.
