摘要: 本文合成和表征了四种新的三核铜(Ⅱ)配合物{[Cu(L)]2[Cu(CH3-ebo)]}(ClO4)2(CH3ebo表示1,2-亚丙基双(草酰胺根),L表示1,10-菲咯啉(phen)(1),5-硝基-1,10-菲咯琳(NO2-phem)(2),2,2'-联吡啶(bpy)(3)和4,4'-二甲基-2,2'-联吡啶(Me2py)(4)).测定了四种配合物的变温磁化率(77-300K),求得交换参数分别为J1=-219.6cm-1,J2=-191.7cm-1,J3=-200.8cm-1,J4=-185.5cm-1,表明Cu(Ⅱ)-Cu(Ⅱ)离子间存在着强的反铁磁交换相互作用. |

Abstract: Four novel trinuclear copper(Ⅱ)complexes have been synthesized and characterized, namely {[Cu(CH3-ebo)][Cu(L)]2}(ClO4)2 where CH3-ebo denotes 1,2-propylenebis(oxamido)and L is 1, 10-phenanthroline(phen)(1), 5-nitro-1, 10-phenanthroline(NO2-phen)(2)2,2'-bipyridyl(bpy)(3)or 4,4'-dimethyl-2,2'-bipyridyl(Me2bpy)(4). The temperature dependence of the magnete susceptibility of these complexes has been studied over the range 75-300K, giving the cxchange intergral J1=-219.6cm-1, J2=-191.7cm-1, J3=-200.8cm-1, J4=-185.5cm-1. The results reveal that a strong antiferromagnetic spin exchange interaction exists between the adjacent cupric ions. |
Keywords: trinuclear complex Cu(Ⅱ)-Cu(Ⅱ)-Cu(Ⅱ)antiferromagnetic interaction |
