| Abstract: The trinuclear nickel(Ⅱ) complex Ni3(C11H11N2O3)2(C5H5N)4 was prepared by the reaction of Ni(OAc)2·4H2O with N-butylsalicylhydrazide Schiff base ligand and characterized by X-ray crystallography. The crystal belongs to triclinic， Mr=930.91， space group P1 with cell parameters a=9.8489(2)?， b=12.3110(2)?， c=18.4035(3)?， α=71.353(2)°， β=76.638(2)°，γ=84.815(2)°，V=2056.72(6)?3，Z=2，Dc=1.503g·cm-3， μ(MoKα) =1.417mm-1， F(000)=964， R=0.0317， wR=0.0868. A total of 5393 independent reflections were collected， of which 4448 reflections with I ≥ 2σ(I) were observed. There are two centrosymmetrical trin-uclear molecules in a unit cell， each molecule exhibits a linear trinuclear metal arrangement with the Ni…Ni…Ni angle of 180°. The interatomic distances between the nickel atoms on the two sides are 9.2030(8)? and 9.1876(9)? for the two molecules， respectively. The central nickel atom adopts an axially elongated octahedral geometry whereas the nickel atoms on the two sides have square-planar coordination environment. CCDC： 194083. |
