The treatment of Schiff base HL [HL＝3,5-(t-Bu)2-2-HOC6H2CH＝N-8-C9H6N] with 1 equiv. n-BuLi in THF followed by reacting with 1 equiv. YbCl3 gives the ion-pairs ytterbium Schiff base complex YbLCl3Li(DME)3 (1). The complex 1 was characterized by elemental analysis, IR spectra, and X-ray structural determination. The crystal data of complex 1 are monoclinic, P21/n space group, a＝1.4855(16) nm, b＝1.3696(13) nm, c＝2.1816(2) nm, α＝90.00°, β＝98.217(3)°, γ＝ 90.00°, V＝4.3748(8) nm3, Z＝4, F(000)＝1868, Mr＝916.17, Dc＝1.397 g·cm-3, μ＝2.364 mm-1, R1＝0.0855, wR2＝0.1863.
