A novel 3D cadmium coordination polymer constructed from hydrazine and benzene-1,2,4,5-tetracarboxylic acid: Synthesis, structure and fluorescent property

A novel three-dimensional (3D) coordination polymer [Cd(bta)0.5(N2H4)(H2O)]·H2O (1) (H4bta = benzene-1,2,4,5-tetracarboxylic acid; N2H4 = 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-μ2-bridging ligand N2H4. In 1, Cadmium atoms are coordinated by bta4− ligands to form sinusoidal ruffling layers and the layer are further linked by hydrazine ligands into 3D network with a (83)(85·10) 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 H4bta and N2H4·H2O. Hydrazine ligands and bta4− 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.Figure optionsDownload as PowerPoint slideResearch highlights
