| Abstract: Under hydrothermal conditions, a manganese complex [Mn(na)2(Dmbpy)(H2O)]·Hna (1) was synthesized by using manganese sulfate, 1-naphthoic acid (Hna), and 4,4'-dimethyl-2,2'-bipyridine (Dmbpy), and characterized by elemental analysis, single crystal X ray diffraction, powder X ray diffraction, infrared spectrum, Hirshfeld surface analysis, and thermogravimetric analysis. The single-crystal X-ray diffraction result shows that 1 belongs to the triclinic crystal system, $P \overline{1}$ space group, and the central metal Mn(Ⅱ) is located in a six-coordinated, distorted trigonal prism configuration. The 2D supramolecular network structure is formed by intermolecular C/O—H…O, C—H…π, and π…π interactions. CrystalExplorer was used to analyze the Hirshfeld surface of 1. The 2D fingerprint of 1 shows that the H…H interaction plays a significant role in maintaining structural stability. Powder X-ray diffraction analysis shows that the synthesized 1 is in pure phase. Thermogravimetric analysis shows that 1 has good thermal stability. The solid-state fluorescence spectrum showed that 1 had a maximum emission wavelength of 423 nm at an excitation wavelength of 347 nm. In the fluorescence sensing experiment, 1 showed selective recognition ability to Fe3+ with a detection limit of 0.52 μmol·L-1. In addition, the mechanism analysis shows that the fluorescence quenching of 1 may be due to the energy-competitive absorption between Fe3+ and 1. |
