Four Isostructural 3d-4f Mixed Metal Organic Frameworks and Their Magnetic Properties

Four new isostructural 3d-4f mixed metal organic frameworks (MOFs) Cu Gd-2 (BDC)(4), compound 1, Cu Ho-2 (BDC)(4), compound 2, Cu Eu-2 (BDC)(4), compound 3, and Cu Dy-2 (BDC)(4), compound 4 were successfully synthesized. The structure, stability, and magnetic properties were analyzed. Each MOF has two lanthanide ions and one copper ion node with terephthalic acid as the organic linker. The lanthanide ions form a dimer with each having a capped trigonal prismatic geometry while the copper ion has a square planar geometry. Each of these MOFs shows varying degrees of antiferromagnetic interactions.
