Through a solid‐state reaction between stoichiometric amounts of a mixed cesium oxide Cs 2 O 1.3 , VS, S, and V 2 O 5 , a polycrystalline powder of CsV 2 S 2 O was obtained. Small single crystals could be grown in a CsCl melt by allowing Cs 2 SO 4 , V metal and S powders to react. The crystals have a plate‐like morphology, consistent with the tetragonal crystal‐structure symmetry [ P 4/ mmm , a = 3.9455(1), c = 7.4785(1) Å]. Magnetic measurements suggest that CsV 2 S 2 O is a temperature‐independent paramagnet, and resistivity data concur with a bad metal. The mixed oxidation state of V on one crystallographic site offers a tentative explanation of the electronic properties of the title compound.
