Abstract

Reaction of the benzimidazole-based ligand 2-(1H-benzoimidazol-2-yl)-4- bromo-6-methoxy-phenol (HL) with LnCl₃ · 6H₂O in a 4:3 mol ratio in refluxing EtOH gave the trinuclear complexes [Ln ₃L₄Cl₄(H₂O)₂] • Cl · H₂O • EtOH (1) (Ln = Tb (a), Er (b), Yb (c)) in 40-59% yields. Under similar conditions, but with the subsequent addition of Zn(OAc)₂-2H₂O to the reaction mixture, complex {[Yb ₃L₄(OAc)₄] • Cl • EtOH}n, (2) can be isolated in 48% yield. 2 has a one- dimensional coordination structure in the solid state. All complexes display intramolecular π-π stacking and hydrogen bonded interactions in the solid state as well as lanthanide ion based luminescence in both solution and the solid.
