摘要：

The equilibrium constants for [Cu2L]4+ + X- = [CuXL]3+ were determined spectrophotometrically in aqueous solution at 25 °C, where L represents the title ligands and X denotes Cl, Br, I and CH3COO. The formation constants of [Cu2XL]3+ thus obtained were unusually large compared to those of common copper(II) complexes with CuX bonds, and decrease in the order Cl- > Br- > I- > CH3COO- for a given L, and taec > taep > taeh for a given X-. The origin of the surprisingly high stabilities was discussed. © 1990.
