Synthesis and structures of luminescent ladder-like lanthanide coordination polymers of 4-hydroxybenzenesulfonate

Abstract

Reaction of sodium 4-hydroxybenzenesulfonate dihydrate (NaL·2H₂O) with LnCl₃·6H₂O (3 ∶ 1) in refluxing methanol gives the novel isomorphous 1-D framework compounds {[LnL₃(H₂O)₂]·2H₂O}_∞ (Ln = Tb, Er and Yb) in 46–60% yields; the structures of the compounds have been determined by X-ray crystallography and their luminescence properties determined.
