We synthesized a new ligand, 2-(3-methoxyphenyl)-1H-imidazo[4,5-f][1,10]phenanthroline (mip), by modifying 1,10-phenanthroline. Then, by coordination of mip and rigid terephthalic acid (bdc) as a mixed ligand, we produced the manganese complex [Mn(mip) 2 (bdc) 2 ] n . The structure of the complex was analyzed by single-crystal X-ray diffraction (XRD), and the complex was characterized by elemental analysis, XRD, thermogravimetric analysis, and infrared spectroscopy. The complex had a one-dimensional chain structure, and a two-dimensional layered structure was formed by the action of the hydrogen bond. It had good thermal stability, and its thermal weight loss curve showed weight loss in each temperature interval. Finally, we studied the fluorescence properties of the complex.
