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 V2O3(SO4)2 were identified. V2O3(SeO4)2 crystallizes in the monoclinic system with the unit cell parameters a = 15.3831(2) Å, b = 5.54096(5) Å, c = 9.71644(7) Å, β =111.886(1)°, V = 768.51 Å3, space group C2/c Полный текст |
