A CuII-GdIII-CuII heterometallic coordination polymer constructed by gadolinium(III) ion and copper(II) Schiff-base building block: Structure and magnetic property

A new 3d-4f heterometallic coordination polymer [Gd(H2O)3(NO3−)(CuL)2] H2O (1) (H3L = glycylglycine, N-[1-(2-hydroxy, phenyl)-propylidene]) has been synthesized and structurally characterized by X-ray single-crystal diffraction. Magnetic studies for 1 reveal that ferromagnetic interactions (JCuGd = 1.30 cm− 1) between Cu(II) and Gd(III) centers are operating within the CuII-GdIII-CuII systems.
