Reaction of the β-diketimine compound (2,6-Me2C6H3)NC(Me)CHC(Me)N(C6H3-2,6-Me2) H (LH, 1) with 1 equiv of n-BuLi/hexane in THF, followed by crystallization from toluene, affords the β-diketiminate lithium ncomplex 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 P2/( 1 ) with a = 1.4036(5), b = 1. 3261(4), c = 1.4248(5)nm, β = 115.437(6)°, V = 2.3950( 13)nm3, and Dc = 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 oxyge natom of THF molecule.
