Research on the Structure of the Tetrahydrofuran Complex of 2,4,6-Trinitro-3-Hydroxypyridine Silver.

ABSTRACT: Silver salts and their complexes play crucial roles as catalysts in organic chemistry. In this study, pyridine-3-ol was employed as the raw material to synthesize the tetrahydrofuran complex of 2,4,6-trinitro-3-hydroxypyridine silver (4) through nitration, salt formation, and other reactions. The structure was characterized using nuclear magnetic resonance spectroscopy (NMR), Fourier transform infrared spectroscopy (FT-IR), elemental analysis (EA), and single-crystal X-ray diffraction (SC-XRD). Its thermal properties were investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The results show that the crystal of compound 4 belongs to the orthorhombic system, with the space group Pna2₁. The unit cell parameters are as fo
