摘要：

A new mononuclear dysprosium complex formulated as [Dy(dppz) (tfnb)(3)]center dot 0.375H(2)O (dppz=dipyrido [3,2-a:2',3'-c]phenazine; tfnb= 4,4,4-trifluoro-1 -(2-naphthyl)-1,3- butanedione) was synthesized, structurally and magnetically characterized. X-ray diffraction study reveals that the central Dy-III ion in the complex adopts an approximately square-antiprismatic (SAP) geometry. The complex shows frequency-dependent ac magnetic susceptibilities, indicating single-ion magnet behavior. (C) 2012 Elsevier B.V. All rights reserved.
