摘要:
An easy way to prepare anhydrous vanadium(II) compounds by reaction of aqueous solutions of [V(H2O)(6)]SO4 with neutral amines is described as well as the X-ray crystal structure determinations of [V(en)(3)]SO4 . CH3OH (I) and V(bpy)(2)SO4 (II). The air-sensitive compound I crystallizes in the trigonal space group P (1) over bar 1c with a=9.009(3), c=9.570(2) Angstrom, V=672.7(3) Angstrom(3) and Z=2. II crystallizes in the monoclinic space group I2/a with a=11.957(2), b=12.071(2), c=14.614(1) Angstrom, beta=101.97(1)degrees, V=2063(1) Angstrom(3) and Z=4.
