Compounds described as V₂O₃(XO₄) ₂, where X = S or Se, were prepared from vanadium(V) oxide mixtures with concentrated sulfuric and selenic acids. The physicochemical properties of the products were studied; for V₂O₃(SeO₄) ₂, the crystal structure was determined by powder X-ray diffraction and neutron diffraction, and its key differences from the structure of V ₂O₃(SO₄)₂ were identified. V ₂O₃(SeO₄)₂ crystallizes in the monoclinic system with the unit cell parameters a = 15.3831(2)?, b = 5.54096(5)?, c = 9.71644(7)?, β = 111.886(1)°, V = 768.51?³, space group C2/c (no. 15).
