Syntheses, Crystal Structure, and Fluorescent Property of a New Cd(II) Complex Constructed from 1,2,4,5-Benzenetetracarboxylate

A new Cd(II) complex {[Cd(btec)0.5(H2O)3]·H2O}n (1) constructed by 1,2,4,5-benzenetetracarboxylic acid (H4btec) has been synthesized under hydrothermal condition and its structure has been determined by means of elemental analysis, IR and single crystal X-ray diffraction. The results show that complex 1 displays an infinite 1-D chain structure in which the four carboxylate groups of each ligand exhibit two kinds of coordination modes. Two carboxylate groups adopt monodentate mode, while the other two display chelating mode. The 1-D chains are further connected by hydrogen bonds forming a 3-D supramolecular structure. In addition, its fluorescent property also has been determined. Supplemental materials are available for this article.
