Заглавие : Synthesis, Structure, and Properties of M3VO2(SO4)2 (M = Rb, Cs) Место публикации : Russian Journal of Inorganic Chemistry. - 2010. - Vol. 55, № 9. - С. 1331-1338: il.

The individuality of the synthesized compounds was proved by X ray and neutron diffraction, vibrational spectroscopy, and microscopic analysis. The X-ray diffraction patterns of M3VO2(SO4)2 were indexed to fit the monoclinic system (space group P2/c, Z = 4) with the following unit cell parameters: a =11.6487(2) Å, b = 8.4469(2) Å, c = 12.1110(2) Å, β = 109.483(1)°, V = 1123.43 Å3 (Rb); a = 12.0546(3) Å, b = 8.7706(2) Å, c = 12.6496(3) Å, β = 109.843(2)°, V = 1257.99 Å3 (Cs). In the crystal structure of M3VO2(SO4)2, [VO2(SO4)2]3– complex anions can be discerned in which the vanadium atom is surrounded by five oxygen atoms: two oxygen atoms form short terminal V–O bonds, and three oxygen atoms are from the two sulfato groups, one of which acts as a monodentate ligand and the other acts as a bidentate chelating ligand Доп.точки доступа: Krasil'nikov, V.
