  Tetranuclear heterometallic cycle Dy2Cu2 and the corresponding polymer showing slow relaxation of magnetization reorientation

  摘要：

  We prepared tetranuclear complexes [{Cu(emg)(Hemg)(ROH)}(2)Dy(hfac)(2)(ROH)}(2)] (abbreviated as [Dy2Cu2]-R; R = Me, Et; H(2)emg=ethylmethylglyoxime) and the corresponding polymer [{Cu(dmg)(Hdmg)}(2){Dy(hfac)(2)(CH3OH)}(2)](n) center dot 2(MeOH) ([Dy2Cu2](n); H(2)dmg = dimethylglyoxime), which were characterized as analogs of the known [Gd2Cu2] monomer and polymer, respectively, by means of X-ray crystallographic analysis. The M-H curves clarified antiferromagnetic coupling between Dy and Cu in the [Dy2Cu2] motif, leading to the Dy magnetic moments aligned parallel ([Cu(down arrow)Dy(up arrow)Cu(down arrow)Dy(up arrow)]). Ac magnetic susceptibility measurements of [Dy2Cu2]-Me and [Dy2Cu2](n), exhibited a chi(ac)' (in-phase) decrease and a concomitant chi('')(ac) (out-of-phase) increase with an increase of frequency. Low-temperature magnetization measurements on [Dy2Cu2], exhibited magnetic hysteresis, which is characteristic of single-chain magnets. (c) 2006 Elsevier Ltd. All rights reserved.

  One-dimensional polymeric complexes consisting of alternating dicopper(II) and digadolinium(III) units exhibited ferrimagnetic behavior which was ascribable to antiferromagnetic coupling across the oximate N–O bridges between the high-spin homodinuclear units.

  由交替出现的二氯化铜（II）和二加钆（III）单元组成的一维聚合物复合物表现出铁磁性，这可归因于高自旋同核单元之间的氧化物 N-O 桥的反铁磁耦合。
