Abstract

Four new complexes, [Zn(btca)(2,2′-bpy)] (1), [Mn(btca)(2,2′-bpy)] (2), [Co(btca)(phen)] (3), and [Cu(btca)(phen)] (4), (H2btca=benzotriazole-5-carboxylic acid, 2,2′-bpy=2,2′-bipyridine, phen=1,10-phenanthroline), were successfully synthesized and characterized by elemental analysis, single crystal X-ray diffraction, and IR spectroscopy. Complexes 14 crystallize in the orthorhombic system with space group of Pbca and show similar 2D layers, which are interlinked to supramolecular networks by π-π stacking interactions. Furthermore, TGA curves show that complexes 14 have good thermal stability. Solid-state fluorescent property of complex 1 was also investigated at room temperature.
