✦ Synopsis

A new series of isostructural 2D layer coordination polymers {[Ln(hisp)(Hhisp)(H 2 O) 2 ]AE2H 2 O} n (Ln = La(1), Tb(2), Er(3), H 2 hisp = 5-hydroxyisophthalic acid) have been synthesized by hydrothermal reactions of lanthanide chloride with 5-hydroxyisophthalic acid under a mild-acid condition (pH 4-5). The 2D layer coordination polymers, which comprise 1D Ln-O-C-O-Ln chains cross-linked by the phenylene moieties of the ligand, are further extended into three-dimensional supramolecular networks by the hydrogen bonding interactions and p-p aromatic stacking interaction. The thermal stability and photoluminescent properties of compound 2 have also been investigated.
