Copper complexes of tripodal κ6N-donor ligands: A structural, EPR spectroscopic and electrochemical study

► Synthesis and characterization of a new tripodal, multidentate N-donor ligand. ► Coordination behavior of two related ligands towards copper(I) and copper(II). ► Copper(II) species show cis bond length distortions and a trigonal twist. ► The findings were supported by electrochemical and EPR spectroscopic studies.
