Abstract

A new compartmental pyrazole-derived chelating ligand, four equivalents of mesitylcopper and stoichiometric amounts of dioxygen lead to the formation of a remarkably stable organometallic framework that can be described as a heteroleptic O-centered cuprate anion [(MesCuI)4(µ4-O)]2− linked via σ-mesityl-bridges to two surrounding binuclear CuI-pyrazolate clamps.
