Abstract

A series of vanadium-(II), -(III) and -(IV) macrocyclic thioether complexes has been synthesized and characterised by analytical, magnetic and spectroscopic methods. The new complexes reported are [{V([9]aneS3)}2(µ-Cl)3]Cl ([9]aneS3 = 1,4,7-trithiacyclononane), [VI2(thf)([9]aneS3)], [VI2(ttob)] (ttob = 2,5,8-trithia[9]-o-benzenophane), [VX3([9]aneS3)] (X = Cl, Br or I), [VX3([10]aneS3)] ([10]aneS3 = 1,4,7-trithiacyclodecane), [VCl3(ttob)], [VCl3([16]aneS4)] ([16]aneS4 = 1,5,9,13-tetrathiacyclohexadecane), [(VX3)2(µ-[18]aneS6)] (X = Cl or Br, [18]aneS6 = 1,4,7,10,13,16-hexathiacyclooctadecane) and [VOCl2(ttob)]. The crystal structures of [VI2(thf[hair space])([9]aneS3)] and [VCl3([9]aneS3)] and EXAFS structural data for [VX3([9]aneS3)] and [VX3([10]aneS3)] are presented and discussed. The acyclic trithioether complexes [VX3{MeC(CH2SMe)3}] (X = Cl or Br) and the complex [VI2(py)4] are also reported.
