By employing the semi-rigid multidentate carboxylic acid ligand 4,4′,4′′-{[(2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene)]tris(oxy)}tribenzoic acid (denoted H3 L), a new lanthanum coordination polymer, namely poly[[bis(dimethylformamide)(μ6-4,4′,4′′-{[(2,4,6-trimethylbenzene-1,3,5-triyl)tris(methylene)]tris(oxy)}tribenzoato)lanthanum(III)] dimethylformamide tetrasolvate 0.25-hydrate], {[La(C33H27O9)(C3H7NO)2]·4C3H7NO·0.25H2O} n or {[La(L)(DMF)2]·4(DMF)·0.25(H2O)} n (DMF is dimethylformamide) (1), was prepared and characterized by single-crystal X-ray diffraction, elemental analysis, thermogravimetric analysis, IR spectroscopy and photoluminescence studies. The asymmetric unit contains one LaIII cation, one anionic L 3− ligand, two coordinated DMF molecules, four free DMF molecules and one-quarter of a free water molecule. Compound 1 possesses (3,6)-connected two-dimensional kgd topology sheets consisting of secondary building units of La2 clusters and L 3− ligands, which further stack into three-dimensional supramolecular networks through π–π interactions. Compound 1 exhibits a photoluminescence emission at room temperature, with a peak at 410 nm, owing to a ligand-centred excited state.
