Abstract

The reaction of HSC6F4H-4 and base with suitable platinum(II) chlorido precursor complexes leads to mononuclear complexes containing diimine ligands [(N<^>N)Pt(SC6F4H-4)(2)], or [(N<^>N)Pt(Me)(SC6F4H-4)] (N<^>N = 2,2'-bipyridine (bpy), dipyrido[3,2-a:2',3'-c] phenazine (dppz) or 11-trifluoromethyl-dipyrido[3,2-a:2',3'-c] phenazine (CF(3)dppz)), cycloocta-1,5-diene (COD) complexes [(COD) Pt(SC6F4H-4)(2)] or [(COD)Pt(R)(SC6F4H-4)] (R = Me, Bn (benzyl) or C6F5), or phosphine complexes cis-[(PPh3)(2)Pt(SC6F4H-4)(2)], [(dppe)Pt(SC6F4H-4)(2)] (dppe = 1,2-bis(diphenylphosphino)ethane) and [(dppb)Pt(C6F5)(SC6F4H-4)] (dppb = 1,4-bis(diphenylphosphino)butane). Reaction of cis-[(DMSO)(2)PtCl2] lead to the labile cis-and trans-[(DMSO)(2)Pt(SC6F4H-4)(2)] which rapidly lose DMSO to yield polymeric [Pt(SC6F4H-4)(2)](m). Reaction of HSC6F4H-4 and KOtBu with K2PtCl4 gave K-2[Pt(SC6F4H-4)(4)]. The new compounds were analysed and characterised by single crystal XRD, H-1, F-19 and Pt-195 NMR and IR spectroscopy. Both single crystal XRD (in the solid) and NMR (in solution) reveal that the ligand strength of the thiolate ligand SC6F4H-4 strongly depends on the further ligands in the complexes. The crystal structures exhibit various interand intra molecular pi stacking interactions of the SC6F4H-4 coligands. The absorption spectroscopy and electrochemistry of the diimine complexes [(N<^>N) Pt(SC6F4H-4)(2)] (N<^>N = bpy, dppz and CF(3)dppz) have been investigated and reveal that the Pt complexes are superior to the recently reported Pd derivatives in view of their application in photoactive materials.
