Abstract

A series of lanthanide coordination polymers, {[Dy3(1,3-BDC) 4(NO3)(phen)3]-2H2O}n (1), {[Dy 2 (1,3-BDC)3(H2O)2] · H 2O}n (2), {[Ln4(1,3-BDC)6(DMF)(H2O) 4] · DMF-2H2O}n (Ln=Tb (3), Ho (4), Er (5), 13-H2BDC = 1,3-benzenedicarboxylate, phen = 1,10-phenanthroline, DMF=N,N-dimethylformamide), have been synthesized and characterized. In coordination polymer 1, each Dy3+ ion is connected to its neighboring Dy3+ ion through bridging carboxyl oxygen atoms of the 1,3-BDC 2- ligands to form a new three-dimensional open-framework structure which the Schläfli symbol of {64 · 82} 2{66}. In coordination polymer 2, center metal dysprosium ions are interlaced and connected through bridging carboxyl oxygen atoms to form an infinite helix chain. Two helix chains are linked through the 1,3-BDC 2- ligand to give rise to the two-dimensional layered structure. Coordination polymers 3-5 are isomorphous, which displays a (3,4)-connected net with the point symbol of {42 · 63 · 8}{42 · 6}. The solid-state photoluminescence properties and lifetimes of the Dy (1 and 2) and Tb (3) coordination polymers have been measured at room temperature.
