General description

3-Methylpyridazine(3-Mepydz) reacts with halogenotrimethylplatinum (IV), [PtXMe3)4], to form complexes of type fac-[PtXMe3(3-Mepydz)2] (X = Cl, Br or I). It undergoes self-association in aqueous solution at acidic, neutral and basic pH . It is a diazaaromatic compound and reacts with bis (1,1,1,5,5,5-hexafluoropentane-2,4-dionato) copper (II) complexes.
