TLDR
In this article, the synthesis and characterization of μ-η 2 : η 2 peroxo dinuclear copper(II) complexes which to oxyhemocyanin (or oxytyrosinase) in their physicochemical properties are presented.Abstract:
The synthesis and characterization of μ-η 2 :η 2 peroxo dinuclear copper(II) complexes which to oxyhemocyanin (or oxytyrosinase) in their physicochemical properties are presented. The low-temperature reaction of a di-μ-hydroxo copper(II) complex [Cu(HB(3,5-i-Pr 2 pz) 3 )] 2 (OH) 2 (8) with H 2 O 2 gave a μ-peroxo complex [Cu(HB(3,5-i-Pr 2 pz) 3 )] 2 (O 2 ) (6)read more

TL;DR: The stabilization of the peroxo complexes is to a large extent attributed to the square pyramidal coordination geometry with the substrate bound in the basal plane, a structural motif enforced by the rigid bispidine backbone.
