Thiol end-capped one-dimensional platinum and palladium complexes

The synthesis and characterisation of acyl-thiol end-capped homobimetallic rigid-rod structured molecules of type [(MeC(O)S4-NCN)Pt ← NCC6H4CN → Pt(NCN4-SC(O)Me)](OTf)2 (6, NCN = [C6H2(CH2NMe2-2,6)2]−) and (MeC(O)S4-C6H4C6H4)(Ph3P)2Pd ← C5H4NCHCHC6H4CHCHC5H4N → Pd(PPh3)2(C6H4C6H44-SC(O)Me)](OTf)2 (9) in which the metal fragments are spanned by π-conjugated organic connecting units is reported.

The synthesis of acyl-thiol end-capped rigid-rod structured transition metal complexes of type [LnM ← N∩N → MLn]2+ (LnM = Pd(PPh3)2(C6H4C6H44-SC(O)Me, Pt[C6H2(CH2NMe2-2,6)24-SC(O)Me)]; N∩N = NCC6H4CN, NC5H4CHCHC6H4CHCHC5H4N) is described. The solid-state structure and the electrochemical behaviour of the latter species are discussed as well.Figure optionsDownload as PowerPoint slide
