Synthesis and characterization of thiovanadyl (V
S2+) complexes
Abstract
The existence of the thiovanadyl ion, VS2+, has been established by reaction of V
O(salen) and V
O(acen)[H2salen =NN′-ethylenebis(salicylideneamine); H2acen =NN′-ethylenebis(acetylacetonylideneamine)] with B2S3 to form the thiovanadyl compounds; infrared and e.s.r. spectroscopy indicate that the V
S bond has greater covalency but is weaker than its vanadyl analogues.
