摘　　要：合成了双苯甲酰丙酮缩乙二胺Schiff碱镍(II)配合物,并测定了该分子晶体结构。晶体属单斜晶系,空间群为P21/n,晶胞参数:a=10.793(2),b=7.909(2),c=22.025(4)?,β=96.68(3),V=1867.4(7)?3,Z=4,Dc=1.441g/cm3。对于3494(I≥2σ(I))个可观察点,最终偏差因子R=0.0281,WR=0.0768.Schiff碱配体的四个配位原子犤O(1)、O(2)、N(1)和N(2)〗与Ni(II)配位,形成平面正方形N2O2Ni配位构型。The title complex Ni (bzacen)(H 2 bzacen =N,N '-dibenzoylacetoneethylenediamin e)was synthesized and characterized by X -ray diffraction analysis.The crystal crystallizes in monoclinic syste m,space group P 2 1 /n.with a=10.793(2),b=7.909(2),c=22.025(4)?,β=96.68(3)°,V=1867.4(7)? 3 ,Z=4,Dc =1.441g /cm 3 .The structure was refined to R=0.0218and W R=0.0768for 3494observed reflectio ns with(I≥2σ(I).The coordination of Ni (II)is coordinated to two oxygen atoms an d two nitrogen atoms from Schiff base bzacen 2- anions,forming a geometry of distorted square.
