Abstract
Abstract A cadmium compound [Cd(C10H5N3O4)(H2O)2] 1, based on 2-(pyridine-3-yl)-1H-4,5-imidazoledicarboxylic acid (H3PyImDC) has been solvothermally synthesized and characterized. Single-crystal structural analysis reveals that the compound crystallizes in the orthorhombic system, Pna21 space group with a = 6.8293(14) A, b = 12.331(3) A, c = 13.732(3) A, V = 1156.3(4) A3 and R1 = 0.0257. In compound 1, two nitrogen and two oxygen atoms of the H3PyImDC ligand coordinate to two Cd2+ ions to form a straight chain which then pack with each other via strong π–π and hydrogen-bondings interactions to construct a three-dimensional (3D) supermolecular structure. Further characterization of compound 1 was performed by X-ray powder diffraction (XRD), thermal gravimetric analyses (TG), infrared (IR) spectra, inductively coupled plasma (ICP) and elemental analyses. The fluorescent property was also evaluated.
