Magnetocaloric effect and slow magnetic relaxation in two only azido bridged ferromagnetic tetranuclear metal clusters

Author affiliations

Abstract

Two MII tetranuclear complexes bridged only by azido, Mn4(N3)7.3Cl0.7L4 (1) and Co4(N3)8L4 (2) in which the four MII ions are precisely coplanar bridged only by six azido anions, were obtained by using 4,5-diazafluoren-9-one (L) as a corner ligand. Magnetic studies indicate that ferromagnetic coupling was conducted by the azido anions between MII ions. At low temperature, 1 exhibits a large magnetocaloric effect and 2 shows field-induced multiple magnetic relaxations.
