A new microporous gadolinium metal-organic framework formulated as Gd(H(3)TDPAT)H2O (1) (H(6)TDPAT = 2,4,6-tris(3,5-dicarboxylphenyl-amino)-1,3,5-triazine) was hydrothermally synthesized. The compound was fully characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, power X-ray diffraction and single-crystal X-ray diffraction. It crystallizes in the hexagonal system, space group P31c with cell parameters a = 12.8501(18) nm, c = 15.709(3) nm and gamma = 120 degrees. The compound was polymeric with Gd-III atoms linked by nine oxygen atoms from six carboxylate groups of H(3)TDPAT(3-)ligands and structurally characterized as a unusual nia topology with (6,6) nodes (Schlafli symbol is {4(12).6(3))(4(9).6(6))). Moreover, the adsorption behavior and magnetic property have been studied and discussed.
