Preparation of new vanadium(II) iodides and crystal structure of hexakis(acetonitrile)vanadium(II)(tetraiodide)
Abstract
The reaction of [VCl3(MeCN)3] with SiMe3I in acetonitrile under reflux yielded a vanadium(II) cation [V(MeCN)6]2+ with a counter ion I42–. The latter is not symmetrical, though linear, and the reasons are discussed. The new compound diiodotetrakis(tetrahydrofuran)vanadium(II) is shown to be a versatile precursor for vanadium diiodides, such as [VI2(Et2PCH2CH2PEt2)2], the structure of which has also been determined.
