Two Novel Cu/Mn Metal-Organic Framework Based on Aromatic Dicarboxylic Acid: Synthesis, Crystal Structure, Thermal Stability, and Luminescence Properties

Two novel transition metal complexes formulated as [Cu(4,5–Himdc)(phen)]n (1) and [Mn(5,6–Hbidc)(H2O)]n (2) (4,5–H3imdc = imidazole–4,5–dicarboxylic acid, 5,6–H3bidc = 1H–benzimidazole–5,6–dicarboxylic acid, phen = 1,10–phenanthroline,) have been synthesized under hydro(solvo)thermal method at a relatively low temperature and characterized by elemental analysis, IR spectroscopy, and X–ray single–crystal diffraction. 1 based on 4,5–H3imdc displays one–dimensional zigzag chain structure. 2 based on 5,6–H3bidc features a two–dimensional framework with 4–connected topology. Thermal stabilities and luminescence properties of the two complexes were investigated.
