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0.458 6(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。
A nickel (Ⅱ) complex [Ni3 (o-nbzshz) 2 (DMF) containing salicyloyl-p-nitro salicyloyl hydrazide (H3-o-nbzshz) and a monodentate N-heterocyclic morpholine (Mf) ) 2 (Mf) 2] · 2H2O, and characterized by elemental analysis, IR, thermal analysis and single crystal diffraction. The title complex is a trinuclear nickel complex with crystallographic central symmetry formed by bridging three metal centers with a hydrazine N-N single bond. The spacing between Ni1 ... Ni2 atoms is 0.458 6 (1) nm. In the complex, the symmetrical Ni1 atoms and the intermediate Ni2 atoms form the planar tetragonal and axial elongated octahedral coordination structures, respectively. The complex is constructed into a two-dimensional supramolecular network structure through intermolecular hydrogen bonding. The magnetic properties of the compounds were also investigated by means of temperature-dependent susceptibility.
