The structural characterisation and elucidation of the electronic structure of the mononuclear Pt(III) complex [Pt([9]aneS_3)_2]~(3+) ([9]aneS_3 = 1,4,7-trithiacyclononane)

摘要

The mononuclear Pt(III) complex, [Pt([9]aneS_3)_2]~(3+) , has been isolated and characterised by X-ray crystallography; its electronic structure determined by EPR spectroscopy and DFT calculations.rnComplexes incorporating a formal Pt(III) centre are rare and are dominated by reports of Pt(III)-Pt(III) or Pt(II)-Pt(III) dimers. These dimers contain Pt centres bound by ligands such as C_6F_5~(-1) and 2-hydroxypyridinate, or Pt centres bound by direct metal-metal bonds as in [Pt_2Cl_6{HN=C(OH)C(CH_3)_3}4]~4 and [Pt_2(μ-PPh_2)_2(C_6F_5)_4].
