A novel three-dimensional (3D) coordination polymer [Cd(bta) 0.5(N 2H 4)(H 2O)]·H 2O ( 1) (H 4bta = benzene-1,2,4,5-tetracarboxylic acid; N 2H 4 = hydrazine) was synthesized hydrothermally and characterized by IR, elemental analysis, TGA and X-ray diffraction analysis. Compound 1 is the first example of 3D coordination compound containing trans- μ 2-bridging ligand N 2H 4. In 1, Cadmium atoms are coordinated by bta 4− ligands to form sinusoidal ruffling layers and the layer are further linked by hydrazine ligands into 3D network with a (8 3)(8 5·10) topology structure. In addition, the thermogravimetric analysis and fluorescent property of compound 1 have been investigated. A novel 3-D cadmium coordination compound was synthesized through hydrothermal reaction between cadmium salt and H 4bta and N 2H 4·H 2O. Hydrazine ligands and bta 4− ligands are connected by Cd cations into simultaneously single-left and single-right-helice channels. Compound 1 would be an excellent candidate as light-emitter applications owing to its strong fluorescence emission. [Display omitted] ► 1 is the first example that N 2H 4 ligands act as bridging ligands in the 3D network. ► H 4bta is very popular to build coordination polymers with fascinating architectures. ► 1 would be an excellent candidate as light-emitter applications.
