Abstract

A metal-organic framework (MOF) based on gadolinium ion (Gd3+) and tricarboxylate ligand, [Gd(BTPCA) (H2O).2DMF.3H(2)O (Gd-BTPCA) (H(3)BTPCA =1,1',1'-(benzene-1,3,5-triyl)tripiperidine-4-carboxylic acid; DMF=dimethylformamide), was synthesized and structurally characterized. The adjacent Gd3+ ions are intraconnected by the carboxylate groups of the BTPCA(3-) ligands to form a 1D Gd3+ ion chain. The 1D Gd3+ ion chains are interconnected by the BTPCA3-ligands, giving rise to a 3D framework with 1D open channel. The magnetic studies indicate that Gd-BTPCA exhibits weak ferromagnetic interactions, and acts as a cryogenic magnetic refrigerant having the magnetic entropy change (-Delta S-m) of 20.40 J kg(-1) K-1 for Delta H =7 T at 3 K.
