2,5-bis(trifluoromethyl)terephthalic acid (H₂L₁) as the main ligand and 1,10′-phenanthroline (L₂) as the co-ligand were reacted with manganese chloride tetrahydrate (MnCl₂·4H₂O), nickel sulfate hexahydrate (NiSO₄·6H₂O) and cobalt nitrate hexahydrate (Co(NO₃)₂·6H₂O) by solvothermal reaction to give the manganese complex [Mn₂(L₁) ₂(L₂)₂]_n (1), the nickel complex {[Ni₃(L₁)₃(L₂)₂(H₂O)₄]·2DMF}_n (2) and the cobalt complex {[Co₂(L₁)₂(DMF)₂]·H₂O}_n (3). The structures were characterized and their properties studied by means of single-crystal X-ray diffraction, infrared spectroscopy, elemental analysis, ultraviolet spectroscopy, fluorescence spectroscopy, thermogravimetric analysis. The single-crystal structure analysis showed that the complexes 1–3 are infinitely extended three-dimensional network-like structures of space groups $P_1^{-}$, $P_1^{-}$, $P{2}_1/n$, respectively. The results of fluorescence analysis and thermogravimetric analysis showed that complexes 1–3 have good thermal stability and fluorescence properties, respectively. Complex 3 can also maintain good thermal stability at 230 °C, and the maximum fluorescence emission wavelength is 370 nm.
