Template-assisted assembly of porous lanthanide coordination polymers with 2-aminoterephthalic acid

Ten isomorphous coordination polymers (CPs) with the formula [Ln2(ATPA)3(DEF)2]n Ln=Ce (1), Pr(2), Nd (3), Eu (5), Gd (6) and [Ln(ATPA)1.5(DEF)]n Ln=Sm (4), Tb (7), Dy (8), Ho (9) and Y(10) (H2ATPA=2‐aminoterepthalic acid and DEF=diethyl formamide) have been synthesized by the self assembly of Ln(III) ions, 2‐aminoterepthalate and DEF under solvothermal condition. These polymers have been systematically characterized by single‐crystal X‐ray diffraction, FTIR, PXRD, thermogravimetric (TGA) and elemental analyses. Structure analyses of CPs 1–10 reveal that all CPs crystallize in the monoclinic space group C2/c system and form 3D framework with difference in coordination numbers. The CPs 1 & 2 exhibit eight coordination numbers whereas CPs 3–10 show seven coordination number with different geometries. TGA indicate thermal stability and robustness of the synthesized CPs. The Sm (4), Eu (5), Tb (7) and Dy (8) polymers emit strong ligand sensitized characteristic f‐f luminescence. Analyses of magnetic susceptibility data of CPs 4, 6, 7 & 8 at variable temperatures and applied magnetic fields reveal weak ferromagnetic interactions at low temperatures.

Two cadmium(II) coordination polymers, namely, [Cd 3 (mphth) 2 (atz) 2 ] n (1) (m-phth = m-phthalate and atz = 3-amino-1,2,4-triazolate) and [Cd(atphth)(H 2 O)] n (2) (atphth = 2-aminoterephthalate), were synthesized and structurally characterized. Compound 1 features a three-dimensional (3D) pillared framework based on two-dimensional (2D) cadmium-benzenedicarboxylate ladders pillared by the tri-
