An unusually stable octanuclear σ-mesityl-bridged μ_4-oxo-copper(I) complex encapsulated by a pyrazolate-based compartmental ligand scaffold

摘要

A new compartmental pyrazole-derived chelating ligand, four equivalents of mesitylcopper and stoichiometric amounts of dioxygen lead to the formation of a remarkably stable organome-tallic framework that can be described as a heteroleptic O-centered cupra
