Cavities for Binding Two Metal Atoms: A Novel Pentanuclear Copper(<scp>I</scp>) Complex with an Anionic, Pentadentate Aryl Ligand with Two <i>ortho</i>‐Chelating Diamine Substituents

Abstract

Two cationic organocopper units 1 stabilized by a CuBr unit is one description of the construction the pentanuclear copper complex [CuBr3(1)2], which is prepared from CuBr and the appropriate lithiated polyamine. The Cu-Cu distance in 1, dictated by the geometric restrictions of the aryl ligand, is quite short (2.456 Å)
