Because MOFs have a serial of advantages such as high crystallinity, high purity, low cost and adjustable structures, they have drawn extensive attention by the researchers all over the world. In this paper, using 4-(4-oxypyridinium-1-yl)phthalic acid (H2L) and Cd2+, two MOFs formulated as CdL(H2O)2 (1) and CdL (2) have been synthesized hydrothermally. The two MOFs have been structurally characterized by single crystal X-ray diffraction. In complexes 1 and 2, L2- ligand adopts different coordination modes, but the two complexes are two dimensional (2D) layer structures. Powder X-ray diffraction data indicates the bulk sample of complex 1 is in pure phase. The UV-vis spectrum and thermally stability of complex 1 have also been measured.
