摘要：
A new 3d-4f heterometallic coordination polymer [Gd(H2O)(3)(NO3-)(CuL)(2)]center dot H2O (1) (H3L = glycylglycine, N-[1-(2-hydroxy, phenyl)-propylidenel) has been synthesized and characterized by IR, elemental analysis, TGA and X-ray single-crystal diffraction. In the coordination polymer, two metallo-ligand Cuts 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 (J(cuGd) = 1.30 cm(-1)) between Cu(II) and Gd(III) centers are operating within the Cu-II-Gd-III-Cu-II systems. (C) 2014 Elsevier B.V.
