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 nucleophilic addition reaction of the ligand Dipp N (Li) SiMe3 (Dipp = 2,6-i Pr-C6H3) with benzonitrile followed by metathesis reaction with magnesium bromide gave the pentacoordinated metal magnesium compound [ 2,6-i Pr2C6H3NC (Ph) N (SiMe3)] 2Mg (THF) (1) which was characterized by1H NMR, 13C NMR and elemental analysis and structural analysis was performed by X-ray single crystal diffraction The crystals are in a distorted triangular bipyramid structure and belong to monoclinic system: P21 / n space group, 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.
