Abstract

Abstract: A series of lanthanide-based coordination polymers (Ln2 (CBOB)2 (OX)·H2 O, where Ln = Gd (1 ), Eu (2 ), Pr (3 ), and Tb (4 ); CBOB = 4-[(4′-carboxybenzyl)oxy]benzoate; OX = oxalate), were obtained from the reaction of H2 OX, H2 CBOB, and Ln(NO3 )3 with the metal salts. Single-crystal measurements show that both1 and2 feature unique 3-D structures with the [Ln(COO)n (C2 O4 )m ] layers connected by CBOB ligands. Moreover, 1, 3, and4 are antiferromagnetic and2 and4 display obvious luminescence emission peaks. Furthermore, quantum Monte Carlo (QMC) simulations and the experimental results reveal that the magnetic coupling parameters of adjacent Gd(III) ions in1 are −0.026(2) and −0.0069(3) cm ─1 .
