A microporous La-metal-organic framework (MOF) has been synthesized by the reaction of La(NO3)(3)center dot 6H(2)O with a ligand 4,4',4''-s-triazine-1,3,5-triyltri-p-aminobenzoate (TATAB) featuring three carboxylate groups. Crystal structure analysis confirms the formation of 3D MOF with hexagonal micropores, a Brunauer-Emmett-Teller (BET) surface area of 1074 m(2)g(-1) and high thermal and chemical stability. The CO2 adsorption capacities are 76.8 cm(3)g(-1) at 273 K and 34.6 cm(3)g(-1) at 293 K, a highest measured CO2 uptake for a Ln-MOFs.
