“…The same sequence was observed in the complexes of trivalent ions. This order is in agreement with the order of stability reported by Irving and Williams (1953), as well as that suggested by Grinberg and Yatsimeriski (1952).…”

The acidity constants of 1,4,7-triazacyclononane hydrochloride {(H 3 -[9]-ane-N 3 ) 3+‚3Cl -} at different temperatures and the stability constants of its chelates with Mn(II), Fe(II), Fe(III), Co(II), Co(III), and Cu(II) have been determined pH-metrically in aqueous solution in the presence of 0.1 M KNO 3 at 20 °C and 32 °C. The mole fractions of different species were calculated and discussed. The thermodynamic parameters for the complexes under investigation were also evaluated.

“…Examination of these results reveals that the stability of 1:1 and 1:2 [M(II):ligand] complexes increases in the general order: Cd(II) < Co(II) < Ni(II) < Cu(II). This is in agreement with the general order of stability of the complexes of these metal ions which was established by Grinberg and Yatsimirski [18] and by Irving and Williams.

The metal ion complexes [Co(II), Ni(II), Cu(II) and Cd(II)] of some azopyrazolopyrimidine derivatives have been prepared and characterized using elemental analyses, molar conductivity, electronic and IR spectra. The azopyrazolopyrimidines are characterized by a high tendency towards complex formation with the neutral molecules coordinating to the metal ion as bidentate ligands. It is concluded that the ligands are bonded to the metal ion through the a-or b-nitrogen atom of the arylazo group and the carbonyl oxygen of the pyrazolone ring where six-or fivemembered chelate rings are formed. The apparent formation constants of the complexes in solution have been determined.
