Synthesis, structures and magnetic properties of linear {Co II2Ln III2} coordination clusters

Abstract

Three linear heterometallic CoII2LnIII2 (Ln = Dy (1), Gd (2), Y (3)) coordination clusters have been synthesized under solvothermal conditions. Single-crystal X-ray diffraction studies revealed that all three compounds are isostructural and crystallize in the monoclinic space group P21/c with Z = 2. The dc magnetic susceptibilities for all three compounds have been measured and the magnetic exchange couplings (for 2) and magnetic anisotropy for CoII ions (for 2 and 3) have been calculated and discussed. Furthermore, the ac magnetic susceptibility measurements have been performed and show that CoII2DyIII2 compounds 1 display single-molecule magnetic (SMM) behavior.
