【Abstract】 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 °.更多还原
