摘  要:合成了含水杨醛缩苯甲酰腙的一维链状镍配合物[Ni(C14H10N2O2)(Mf)]n(Mf=C4H9NO,即吗啡啉),通过元素分析,红外、电子光谱和X-射线单晶衍射进行了表征.晶体属单斜晶系,空间群为P21/c,a=0.9708(4)nm,b=1.4783(7)nm,c=1.2275(4)nm,β=95.728(14)°,V=1.7528(12)nm3,Z=4,Mr=384.07,Dc=1.455 g.cm-3,μ=1.129 mm-1,F(000)=800,R=0.0759,wR=0.2155.中心镍离子与水杨醛缩苯甲酰腙配体提供的2个氧原子与1个氮原子以及1个配位吗啡啉的氮原子配位,形成了N2O2的平面四边形的配位构型.晶体内每个配合物分子通过分子间氢键与相邻另一个配合物分子缔合成一个沿c轴方向的一维链状结构,N…N氢键键长为0.3239(10)nm,N-H…N氢键键角为173.56°.The title nickel(Ⅱ) complex [Ni(C14H10N2O2)(Mf)]n with salicylaldehyde benzoylhydrazone(H2L) were prepared and characterized by elemental analysis,infra-red spectrum,electronic spectrum and X-ray single diffraction.The crystallographic data were as follows: monoclinic system,space P21/c,a=0.9708(4) nm,b=1.4783(7) nm,c=1.2275(4) nm,β=95.728(14) °,V=1.7528(12) nm3,Z=4,Mr=384.07,Dc=1.455 g·cm-3,μ=1.129 mm-1,F(000)=800,R=0.0759,wR=0.2155.The Ni(Ⅱ) center was coordinated by three donors(two oxygen atoms and one nitrogen atom) from the ligand and one nitrogen atom from the coordinated morpholine,forming a square-planar N2O2 coordination geometry.Every two molecules related by centrosymmetric operation in the title complex were connected through intermolecular hydrogen bonds,forming one-dimensional chain.The hydrogen bond length of N…N was 0.3239(10) nm,and the bond angle of N-H…N was 173.56 °.
