摘要：
A dysprosium(III) compound, {[DY1.5(acac)(1.5)(L)(3)] [DY1.5(acac)(1.5)(L)(3)]center dot 0.5H(2)O}(n) (1) (acac = acetylacetone, HL = 2-[(4-chlorophenyl)imino]methyl]-8-hydroxyquinoline), has been synthesized, structurally and magnetically characterized. The X-ray structural analysis exhibits that the compound 1 is composed of two crystallographically independent [Dy-1.5(acac)(1.5)(L)(3)] moieties. The central Dy(III) ion is eight-coordinated with one bidentate acetylacetone and two Schiff base ligands (HL). Magnetic measurements indicated that two magnetic relaxation processes were clearly observed in 1, typical of double magnetic relaxation of SMM behaviors. (C) 2016 Elsevier B.V. All rights reserved.
