| 摘要: 合成了1个含水杨酰基缩对硝基水杨酰肼(H3-o-nbzshz)和单啮N-杂环分子吗啡啉(Mf)的镍(Ⅱ)配合物[Ni3(o-nbzshz)2(DMF)2(Mf)2]·2H2O，并通过元素分析、红外、热分析以及单晶衍射等手段进行表征。标题配合物是由肼基N-N单键桥联3个金属中心形成的具有晶体学中心对称性的三核镍配合物结构，Ni1…Ni2原子间距为0.4586(1)nm。在配合物中，对称的Ni1原子与中间的Ni2原子分别形成平面四方形和轴向伸长的八面体的配位构型。配合物通过分子间氢键作用构筑成二维超分子网络结构。并通过变温磁化率研究了化合物的磁性质。 |

| Abstract: Anickel(Ⅱ) complex [Ni3(o-nbzshz)2(DMF)2(Mf)2]·2H2O with N-o-nitrobenzoylsalicylhydrazide (H3-o-nbzshz) and monodentate N-donor heterocycle, morpholine (Mf) has been synthesized and characterized by elemental analysis, IR, TGAand single-crystal X-ray diffraction. The complex reveals a centrosymmetric trinuclear structure, in which the three nickel(Ⅱ) centers are bridged by two N-Nsingle bridges. The Ni1…Ni2 separation is 0.4586(1) nm. The central nickel atom adopts an axially elongated octahedral geometry whereas the nickel atoms on the two sides have square-planar coordination geometry. The complex forms an infinite 2Dnetwork structure by intermolecular hydrogen bonds. The magnetic property has been investigated by variable temperature magnetic susceptibility measurement. CCDC: 954042. |
