Abstract

The crystal structure of a 1: 1 adduct, Li[N(SiMe₃)₂]·OEt₂, has been determined by X-ray diffraction. Crystals are tetragonal, space group P4̄n2, with a = 9.762(6), c = 17.280(9) Å, and Z = 4. The lattice contains dimeric molecules of symmetry 222 with the silazane groups functioning as the bridging ligands [Li-N 2.055(5) Å, Li-N-Li 75.1(2)°, N-Li-N 104.9(3)°]; the lithium atoms are three-co-ordinate [Li-O 1.943(6) Å, O-Li-N 127.5(1)°].
