| Abstract: | Two new 4f-3d heterometallic coordination polymers Gd2Co(L1)3(ox)(H2O)4]·2.5H2O (1, L1 = pyridine-2,5-dicarboxylate anion, ox = oxalate dianion) and GdNi(L2)2(ox)0.5(H2O)3]·3H2O (2, L2 = pyridine-2,3-dicarboxylate anion) were successfully synthesized under hydrothermal conditions. In compound 1, one dimensional heterometallic and lanthanide infinite sheets were constructed with sole L1 spacers and L1-ox mixed bridges, respectively. While similar one dimensional heterometallic infinite sheet and normal lanthanide infinite zigzag chain were formed based on sole L2 and L2-ox mixed bridges, respectively in compound 2. Both of the two compounds exhibited new and interesting three dimensional topologies. In addition, the magnetic properties of the two compounds were analyzed via solid-state dc magnetic susceptibility measurements. |
