In the past few decades, metal-organic frameworks (MOF) have attracted much attention of chemists all over the world, because of their esthetic topological architectures and potential applications in many fields such as gas storage and separation, catalysis, magnetism, optics, ion conductivity, luminescence and drug delivery. The structures of these crystalline materials consist of metal ion, organic ligand and solvents. Aromatic polycarboxylate ligands as a kind of multidentate O-donor ligands, have been extensively employed in the preparation of MOFs.

In this work, the title MOF was synthesized by mixing calcium salt and benzene-1,2,4,5-tetracarboxylic acid in a mixture of water and alcohol; which was characterized by X-ray diffraction, FT-IR and photoluminescence spectroscopy methods.
