摘　　要：Four new complexes, [Zn（btca）（2,2＇-bpy）] （1）, [Mn（btca）（2,2＇-bpy）] （2）, [Co（btca）（phen）] （3）, and [Cu（btca）- （phen）] （4）, （Hzbtca=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 spectros- copy. Complexes 1-4 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 1-4 have good thermal stability. Solid-state fluorescent property of complex 1 was also investigated at room temperature.Four new complexes, [Zn（btca）（2,2＇-bpy）] （1）, [Mn（btca）（2,2＇-bpy）] （2）, [Co（btca）（phen）] （3）, and [Cu（btca）- （phen）] （4）, （Hzbtca=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 spectros- copy.
