Abstract
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 characterized by IR, elemental analysis, TGA and X-ray single-crystal diffraction. In the coordination polymer, two metallo-ligand CuLs are connected with Gd3+ ion to form a 1-D chain via carboxylate and carbonyl oxygen. The neighboring Cu–Gd–Cu chains are further connected by hydrogen bonds to form a two-dimensional structure. Magnetic studies for 1 reveal that ferromagnetic interactions (JCuGd=1.30cm−1) between Cu(II) and Gd(III) centers are operating within the CuII–GdIII–CuII systems.
