Abstract A family of rare 2p-3d-4f ladder-like one-chain complexes namely [LnCu(hfac)5NIT-Ph-p-OCH2trz·0.5C6H14]n (Ln = Er (1), Ho (2), Yb (3) ; NIT-Ph-p-OCH2trz = 2-(4-((1H-1,2,4-triazol-1-yl)methoxy)phenyl)-4,4,5,5-tetra- methylimidazoline-1-oxyl-3-oxide; hfac = hexafluoroacetylacetonate) have been successfully synthesized simultaneously through reacting nitronyl nirtroxide radical NIT-Ph-p-OCH2trz with Cu(hfac)2 and Ln(hfac)3. The structures of complexes of 1–3 were elucidated by single-crystal X-ray structural analysis and the result show that all complexes feature ladder-like chain structures. Nonzero out-of-phase signals are observed for Ho derivatives (2) indicating single-chain magnet behavior.
