✦ Synopsis

Three new supramolecular lanthanide coordination polymers, {[Eu(SA) 1.5 (phen)]$H 2 O} n (1), and [Ln(SA) 1.5 (phen)] n [LnZEr (2); Yb (3)] were obtained by hydro-solvothermal reactions of lanthanide chlorides with succinic acid (H 2 SA) and 1,10-phenanthroline (phen), and characterized by single crystal X-ray diffraction, elemental analysis and IR spectrum. Complexes 1-3 also have 2D networks which are further architectured to form 3D supramolecular structures by hydrogen bonds and p-p aromatic interactions, of which 1 has 1D channels. The H 2 SA ligands are all completely deprotonated and exhibit tetra-and pentadentate coordination modes in the titled complexes. The photoluminescence property of 1 was investigated.
