A series of lanthanide-based coordination polymers (Ln2(CBOB)2(OX)·H2O, 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 H2OX, H2CBOB, and Ln(NO3)3with the metal salts. Single-crystal measurements show that both1and2feature unique 3-D structures with the [Ln(COO)n(C2O4)m] layers connected by CBOB ligands. Moreover,1,3,and4are antiferromagnetic and2and4display 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 in1are −0.026(2) and −0.0069(3) cm─1.
