One-dimensional lanthanide−transition heterometallic chains of squares, {LnNi2L3(HL)(DMF)4(ClO4)4·S} (Ln = Gd and Tb; HL is the Schiff base obtained by the condensation of 2-pyridylaldehyde with isonicotinic hydrazide N-oxide; S = solvent) and {LnNi2L4(DMF)4(ClO4)3·S} (Ln = Dy; S = solvent), were synthesized by self-assembly between well-designed orthogonal metalloligands [Ni(HL)L]+ and the Ln(III) ions, which act as the bridging units and nodes, respectively.
