Summary:The hydrothermal reaction of La(NO3)3 with 2-pyrimidinecarbonitrile in water yields a 3D metal-organic coordination framework [La2(ox)3(H2ox)(H2O)2](H2O)8 (ox=oxalate). This compound has channels with hosted water molecules inside and shows an intense photoluminescence emission at room temperature in the solid state. Due to the great channels that this compound possesses we have analyzed the experimental and simulated adsorption properties. This is one of the few examples of three-dimensional lanthanum polymers based only on oxalate ligand. The hydrothermal reaction of La(NO3)3 with 2-pyrimidinecarbonitrile in water yields a 3D metal-organic coordination framework [La2(ox)3(H2ox)(H2O)2](H2O)8 (1) (ox=oxalate). This compound has channels with hosted water molecules inside and shows an intense photoluminescence emission at room temperature in the solid state. Due to the great channels that this compound possesses we have analyzed the experimental and simulated adsorption properties. This is one of the few examples of three-dimensional lanthanum polymers based only on oxalate ligand.
