The influence of the third components – diantipyrylphenylmetane and oxyquinoline on the complexes formation of nickel(II) with 3-(1-phenyl-2,3-dimethiylpirozolon-5)azopentadion-2,4 has been investigated. The single (NiR) and mixed ligand (Ni(II)–R-DАPFМ and Ni(II)–R–Ох) complex compounds form at pH 7.6 and 6 respectively. The ratio of the reacting components in the composition of the single 1:2 and mixed ligand 1:2:1 compounds has been established. The interval of subjecting Beer’s law has been determined.

Keywords : nickel(II), azoderivatives, mixed ligand complexes, diantipyrylphenylmetane, oxyquinoline
