The complexation processes of Cu (II), Co (II) and Ni (II) ions in ammonia solutions with diacylhydrazines of non-pentane acid (DAH): 1,2-dineopentanoyl- (DNH) and 1-neopentanoyl-2-benzoylhydrazine (NBH) were studied. Using saturation, equilibrium shift, curve intersection, and conductometric titration, the formation of complex compounds with the ratios [M (II)]:[DAH] = 1:1 and 1:2 was established. The DNH complex with Cu (II) (1:1) was preparatively isolated, the composition of which was confirmed by the data of IR spectroscopy, elemental and thermal analyzes. The SP precipitate of the complex and the complexation reaction constant are calculated
