    Abstract

    5-(4-pyridyl) phenyl substituted functionalized nitronyl nitroxide biradical ligand holds MnII ions and TbIII/HoIII ions together to yield 3d-4f-biradical heterospin clusters, namely, [Ln2Mn2(hfac)10(NITPhPybis)2] [Ln=Tb 1, Ho 2], wherein, two NITPhPybis radicals ligate two MnII ions via two NO groups and two nitrogen-atoms from pyridine rings. At the same time, each NITPhPybis encapsulates one LnIII ion through chelating mode with adjacent NO groups, generating an annular centrosymmetric heterometallic tetranuclear system. In addition, the direct current and alternating current magnetic properties and luminescent behavior were systematically studied. Magnetodynamic studies uncover that the cluster 1-TbMn exhibits slow magnetic relaxation. The fluorescence of two polynuclear clusters show the characteristic fluorescence of TbIII or HoIII ions.
