Chiswell, B. published the artcilePlatinum complexes of some deprotonatable tridentate ligands, Related Products of pyridine-derivatives, the publication is Australian Journal of Chemistry (1968), 21(8), 1997-2001, database is CAplus.
Pt(II) and Pt(IV) complexes of 1,3-bis(2-pyridyl)-1,2-diazaprop-2-ene and ligands of similar structure, but with Me “blocking groups” adjacent to the pyridine N atoms, were studied. In neutral solution, these ligands lose a proton upon interaction with either Pt(II) or Pt(IV) salts to yield highly colored complexes soluble in organic solvents. Protonated compounds of both oxidation states can be obtained, but such compounds are unstable in neutral solution and readily yield deprotonated complexes.
