摘　　要：配体(Dipp)N(Li)SiMe3(Dipp=2,6-i Pr-C6H3)与苯腈进行亲核加成反应,再和溴化镁进行复分解反应,得到了五配位金属镁化合物[2,6-i Pr2C6H3NC(Ph)N(SiMe3)]2Mg(THF)(1),该化合物通过1 H NMR,13 C NMR和元素分析进行了表征,并用X-ray单晶衍射进行了结构分析.其晶体呈扭曲的三角双锥结构且属于单斜晶系:P21/n空间群,a=11.759(6),b=28.216(15),c=14.875(7),β=96.913(8)°,V=4 900(4)3,Z=4,R1=0.0871,GOF=0.985.The five-coordinated benzamidinate magnesium complex [2,6-iPr2C6H3NC(Ph)N(SiMe3)]2Mg(THF) was obtained via the nucleophilic addition reaction of(Dipp)N(Li)SiMe3(Dipp=2,6-iPr-C6H3) with benzonitrile and salt metathesis reaction with MgBr2·2THF.The complex was characterized by X-ray,1H NMR,13C NMR and elemental analysis.The crystal of the title complex shows a distorted trigonal bipyramidal structure and belongs to monoclinic P21/n space group,with a = 11.759(6),b=28.216(15),c=14.875(7);β=96.913(8)°;V = 4 900(4)3,Z = 4,R1 = 0.087 1,GOF = 0.985.CCDC:867344
