3′-c]phenazine) have been isolated by reactions of EIFD, DyCl3·6H2O and a series of auxiliary ligands. X-ray crystallographic analysis reveals that complexes 1–4 are all eight-coordinated mononuclear structures. Magnetic studies indicate that complexes 1–4 are all single-molecule magnets. Notably, the auxiliary ligands play an essential role in regulating their magnetism. The corresponding structural and magnetic
