Synthesis, characterizations and structure of orthometallated Pt(II) and Pt(IV) complexes: Oxidative addition to C,N,N,O coordinated Pt(II) complexes

摘要

Reactions of 2-(arylazo)-1-N-salicylidene phenylamine, H_2L, 1, [H represents the dissociable protons upon complexation], with K_2PtCl_4 afforded orthometallated complexes of composition [Pt(L)], 2 where the Pt(II) is coordinated by the tetradentate (C,N,N,O) ligand, L~(2-). Reaction of the precursor complex [Pt(L)] with I_2 afforded octahedral complexes of composition [PtI_2(L)], 3. All the complexes were characterized unequivocally. X-ray crystal structure of [Pt(L~1)] and [Pt I_2(L~1)] have been determined.
