摘　　要：Reaction of the β diketimine compound (2,6 Me 2C 6H 3)NC(Me)CHC(Me)N(C 6H 3 2,6 Me 2)H (LH,1) with 1 equiv of n BuLi/hexane in THF,followed by crystallization from toluene,affords the β diketiminate lithium complex LLi(THF)(2)in high yields.The crystal structure of complex 2 was determined by X ray diffraction method.It crystallizes in monoclinic,space group P 2/(1)/ n with a =1 4036(5), b =1 3261(4), c =1 4248(5)nm, β =115 437(6)°, V =2 3950(13)nm 3,and D c =1 066Mg·m -3 for Z =4.In the structure,the metallacycle is almost fully planar,and the Li atom is coordinated by two nitrogen atoms of the β diketiminate ligand and one oxygen atom of THF molecule.Reaction of the β diketimine compound (2,6 Me 2C 6H 3)NC(Me)CHC(Me)N(C 6H 3 2,6 Me 2)H (LH,1) with 1 equiv of n BuLi/hexane in THF,followed by crystallization from toluene,affords the β diketiminate lithium complex LLi(THF)(2)in high yields.The crystal structure of complex 2 was determined by X ray diffraction method.It crystallizes in monoclinic,space group P 2/(1)/ n with a =1 4036(5), b =1 3261(4), c =1 4248(5)nm, β =115 437(6)°, V =2 3950(13)nm 3,and D c =1 066Mg·m -3 for Z =4.In the structure,the metallacycle is almost fully planar,and the Li atom is coordinated by two nitrogen atoms of the β diketiminate ligand and one oxygen atom of THF molecule.
