  Synthesis, spectral characterization and electrochemical studies of mixed-ligand complexes of platinum(II) with 2-(arylazo)pyridines and catechols. Single-crystal X-ray structure of dichloro{2-(phenylazo) pyridine}platinum(II)

  摘要：

  The reaction of 2-(arylazo)pyridines, RH4C6N=NC5H4N (aap, 1 where R=H (pap), p-Me (p-tap), p-Cl (p-Clpap)) with K2PtCl4 in 1:2 boiling acetonitrile-water affords orange-red complexes of the type Pt(aap)Cl-2 (2). The IR spectrum shows two v(Pt-Cl) stretches suggesting cis-PtCl2 configuration. The structural confirmation was carried out by an X-ray diffraction study of Pt(pap)Cl-2 (2a). The addition of catechols to a chloroform-methanol solution of Pl(aap)Cl-2 in the presence of Et3N yielded green colored mixed-ligand complexes of the formula Pt(aap)(O,O) (O,O = catecholate (cat) (3), 4-tert-butylcatecholate (tbcat), (4), 3,5-di-tert-butylcatecholate (dtbcat) (5) and tetrachlorocatecholate (tccat) (6)). The complexes were characterized by elemental analyses, IR, W-Vis-NIR and H-1 NMR spectral data. Electronic spectra exhibit a ligand-ligand charge transfer (LLCT) transition at NIR region; the position and symmetry of the band depend on the type of substituent on the catechol frame. This is qualitatively assigned as 3b(1)(cat)-->pi*(aap) transition. Cyclic voltammogram of the complexes show four successive redox responses: two couples positive to SCE are referred to as oxidation of catechol to semiquinone and semiquinone to quinone, respectively and two couples negative to SCE correspond to azo reductions.
