Synthesis, Crystal Structures and Magnetic Properties of Two Lanthanide Coordination Polymers with 3-Carboxyphenoxyacetatic Acid

摘要

Two lanthanide(III) coordination polymers: [Ln(3-CPOA)_(1.5)(phen)]n (Ln = Ce (1), Pr (2), 3-H2CPOA = 3-carboxyphenoxyacetatic acid, phen = 1,10-phenanthroline) have been hydrothermally synthesized and characterized by single crystal X-ray diffraction and magnetic measurements. Both polymers are isostructrural and crystallize in monoclinic space group P21/c. Single-crystal X-ray diffraction studies show that two complexes possess 3D framework structures based on a binuclear unit. Magnetic studies for two complexes show a stronger magnetic coupling between the lanthanide ions. (CCDC: 895012 for 1; 895013 for 2).
