Abstract
The synthesis of m-xylyltrien(l,3-bis(2,5,8,11-tetraazaundecyl)-henzene) is described. Potentiometric equilibrium studies of the stability constants of this binucleating ligand with Cu(II), Co(II) and Ni(II) are reported.1 Equilibrium data are determined for the formation of mononuclear and dinuclear chelates of these metal ions, as well as several protonated and hydroxo chelates. The oxygenation constant of the binuclear Co(II) complex is reported. The cobalt dioxygen complex was found2,3 to undergo first order degradation at 50°C and 0.1 M ionic strength. Rate constants are reported as a function of p[H].
