“…The enhanced luminescence intensity can be attributed to strong interactions between deprotonated H 2 DCImPyO À and Cd 2þ , which imparts the rigidity of H 2 DCImPyO À and reduces non-radiative loss. The same luminescence occurred in other H 3 PyImDC based compounds [33,38,39].…”

Three metal-organic frameworks, [Eu(C 10 H 6 N 3 O 5 ) 3 (H 2 O) 2 ] Á H 2 O (1), [Tb(C 10 H 6 N 3 O 5 ) 3 (H 2 O) 2 ] Á H 2 O (2), and [Cd(C 10 H 6 N 3 O 5 ) 2 Cl 2 ](3) based on T-shaped tripodal ligands 3-(4,5-dicarboxy-1H-imidazol-2-yl)pyridine-1-oxide and 4-(4,5-dicarboxy-1H-imidazol-2-yl)pyridine-1-oxide (H 3 DCImPyO), have been synthesized by the hydrothermal method and characterized by elemental analysis, IR, and single-crystal X-ray structure analysis. The diverse coordination modes of H 3 DCImPyO ligands have afforded the three compounds. Complexes 1 and 2 are isomers and the Ln (Ln ¼ Eu or Tb) atoms have coordination number eight with a distorted square prism geometry. The partly deprotonated H 2 DCImPyO À ligands display three different coordination modes to link Ln (Ln ¼ Tb or Eu) into 1-D double chains. In 3, Cd(II) lies on an inversion center and displays a slightly distorted octahedral coordination. All three compounds exhibit strong fluorescent emissions in the solid state at room temperature.

“…9,10 There is growing interest in 2-(pyridin-4-yl)-1H-imidazole-4,5-dicarboxylic acid as a bridging heterocyclic carboxylic acid ligand with nitrogen and oxygen atom donors. 11,12 It can be partly or fully deprotonated by controlling the pH carefully and hence may result in a large diversity of supramolecular architectures. 13 CO 2 is an important raw material in preparing carboncontaining compounds.…”

Two Novel Sm and La Metal-Organic Frameworks Suggesting the Reductive Coupling of Carbon Dioxide (CO₂) to Oxalate (C₂O₄²-): {[Ln(HPIDC)•(μ₄-C₂O₄)_0.5·H₂O]·2H₂O}_n.(Ln=Sm or La)

Complexes formulated as {[Ln(HPIDC)(μ4-C2O4)0.5(H2O)]·2H2O}n [Ln=Sm or La; H3PIDC=2-(pyridin-4-yl)-1H-imidazole-4,5-dicarboxylic acid] have been synthesised under hydrothermal conditions. The complexes are both built up from T-shaped 3-connected HPIDC2- and 4-connected metal nodes and contain bridging oxalate (C2O42-) ligands, which might have been formed by the reductive coupling of CO2 molecules released from the HPIDC2- ligands through C-C bond cleavage.
