  structure-dependent magnetic properties are investigated. The two Dy2 compounds display only slight variations in the coordination geometries of the center Dy(III) ion but display remarkably different single-molecule magnet behaviors with the anisotropic barriers (ΔE/kB) of 9.91 K for 1 and 20.57 K for 2. The different magnetic relaxation behaviors of the two Dy2 complexes mainly originate from the different chemical

  Two dinuclear lanthanide(III) complexes, namely, [Ln(2)(bfa)(4)L-2].CH2Cl2 (Ln(III) = Gd (1) and Tb (2), bfa = benzoyltrifluoroacetone and HL = 2-[[(4-methylphenyl)imino] methyl]-8-hydroxyquinoline), have been synthesized, structurally and magnetically characterized. 1 and 2 are phenoxo-O bridged dinuclear complexes and each center Ln(III) ion is eight-coordinated with two bidentate bfa and two mu(2)-O bridging 8-hydroxyquinoline Schiff base ligands. Magnetic studies reveal that 1 displays cryogenic magnetic refrigeration property (-Delta S-m = 18.5 J kg K-1 (-1) for Delta H = 7 T at 2 K); while 2 exhibits single-molecule magnet behavior with the anisotropic barriers (Delta E/k(B)) of 9.93 K.

  Two series of new lanthanide dinuclear complexes having formulae, [Ln(2)(hfac)(4)(L1)(2)] (Ln = Tb (1), Er (2) and Lu (3), hfac = hexafluoroacetylacetone and HL1 = 2-[4-methylaniline-imino]methy11-8-hydroxyquinoline) and [Ln(2)(hfac)(4)(L2)(2)] (Ln = Tb (4), Ho (5) and Er (6), hfac = hexafluoroacetylacetone and HL2 = 2-[(3,4-dimethylaniline)-imino]methy11-8-hydroxyguinoline), have been successfully synthesized and studied interms of their magnetic properties. Magnetic studies reveal that 1 and 4 shows distinct slow magnetic relaxation. Indeed, no out -of -phase alternating current (ac) signal is noticed for 1, whereas 4 shows a slow relaxation of magnetization with energy barriers (Delta E/k(B)) of 6.84 K while application of an external dc field (2000 Oe).
