Cu(II) hyperfine lines are obtained in these complexes even at room temperature, which is rare for a non-dilute Cu(II) complex. No ligand hyperfine (LHF) structure from bonded nitrogen is obtained in polycrystalline samples of these complexes at the above temperatures to allow the σ-bond strength to be estimated more accurately.
