Preparation of new vanadium(II) iodides and crystal structure of hexakis(acetonitrile)vanadium(II)(tetraiodide)
摘要:
The reaction of [VCl3(MeCN)(3)] with SiMe(3)I in acetonitrile under reflux yielded a vanadium(II) cation [V(MeCN)(6)](2+) with a counter ion I-4(2-). The latter is not symmetrical, though linear, and the reasons are discussed. The new compound diiodotetrakis (tetrahydrofuran)vanadium (II) is shown tb be a versatile precursor for vanadium diiodides, such as [VI2(Et(2)PCH(2)CH(2)PEt(2))(2)], the structure of which has also been determined.
