摘要：

The interaction of phosphate with the mono- and binuclear cobalt(II) complexes of [30]aneN10 (1,4,7,10,13,16,19,22,25,28-decaazacyclotriacontane) has been studied by potentiometry in 0.15 mol dm-1 NaClO4 solution at 298.15 K under anaerobic conditions. The stable species [CoH2([30]aneN10)PO4]+, [CoH4([30]aneN10)PO4]3+, [Co2H([30]aneN10)PO4]2+, [Co2H2([30]aneN10)PO4]3+ and [Co2H3([30]aneN10)PO4]4+, where the phosphate anion is directly bound to the metal ions or acts as a second sphere ligand, are formed and their stability constants have been deter-mined. The results obtained allowed for the selection of suitable conditions for the study of dioxygen uptake.
