| Abstract: A complex [Ce(pydc)(Hglu)]n (H2pydc=2,5-pyridinedicarboxylate acid, H2glu=glutaric acid) was hydro-thermally synthesized. It was characteristic by elemental analysis, IR spectroscopy, and single-crystal X-ray diffraction. The crystal belongs to monoclinic system, space group P21/c. The cell parameters are: a=0.996 59(7) nm, b=1.555 86(11) nm, c=0.864 38(6) nm, β=92.419(10)°, V=1.339(16) nm3, Dc=2.164, Z=4. The structure of the complex reveals that the title complex is an lanthanide Ce complex with both 2,5-pydc and glu as mixed ligands and it is a three-dimensional framework. In the formation of the complex both ligands act as bridging ligands, by the linking of the two ligands, exhibiting a complicated 3D framework containing 1D infinite -Ln-O-Ln- chain structure. In addition, we have investigated the thermal stability. CCDC: 759315. |
