Synthesis, chemical properties, and electrochemical behavior of a Pt(II) complex bearing a benzenediamide-derived ligand
摘要:
The reaction of [PtCl2(cod)] [(cod = 1,5-cyclooctadiene) with Ph-Ph'-Ph'(2,3-NH2)-Ph'-Ph (LH2) (Ph = phenyl; Ph' = p-phenylene; Ph'(2.3-NH2) = p-phenylene-2,3-diamine) gave a new platinum(II) complex bearing a pi-conjugated Ph-Ph'-Ph'(2,3-NH)-Ph'-Ph (L. Ph'(2,3-NH) = p-phenylene-2,3-diamide) ligand, [Pt(L)(cod)], with the liberation of 2 HCl. The X-ray structure determination of the complex confirmed the coordination of the ligand to the platinum center in an o-benzenediamide form. The cyclic voltammogram of the complex showed reversible two-step [Pt-bda](0)/[Pt-sqdi](+) and [Pt-sqdi](+)/[Pt-bqdi](2+) redox couples (bda = o-benzenediamide, sqdi = o-semiquinone diimine, bqdi = o-benzoquinone diimine).
