Abstract
A binuclear Zn(II) complex [Zn2(SDBA)2(DPA)2.2H2O] (1) (DPA = di-2-pyridylamine, H2SDBA = 4,4′- sulfonyldibenzoic acid) is synthesized and characterized using single crystal X-ray diffraction, IR spectroscopy, and elemental analysis. The single crystal X-ray diffraction analysis reveals that complex 1 is a binuclear zinc(II) complex. The binuclear molecules are further connected by three types of N–H...O, C–H...O, and O–H...O hydrogen bonds, generating a three-dimensional supramolecular structure. Meanwhile, S–O...π interactions further consolidate the three-dimensional supramolecular framework of 1. In addition, the thermal stability and luminescent properties of the title complex are briefly investigated. The luminescence measurements reveal that complex 1 exhibits fluorescent emission in the solid state at room temperature.
