Synthesis and Structure of Ion-Pairs Ytterbium Chloride Bearing Tridentate [O,N,N] Schiff-Base Ligand

Abstract

The treatment of Schiff base HL [HL＝3,5-(t-Bu) 2 -2-HOC 6 H 2 CH＝N-8-C 9 H 6 N] with 1 equiv. n-BuLi in THF followed by reacting with 1 equiv. YbCl 3 gives the ion-pairs ytterbium Schiff base complex YbLCl 3 Li(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, P2 1 /n space group, a＝1. 4855(16) nm, b＝1.3696(13)
