| Abstract: | Two complexes with pyrazine polycarboxylic acid, namely {[Cu2(pztc)(4,4'-bpy)(H2O)4]·6H2O}n (1), {(H2bpe)[Cd(pztc)(H2O)2]·2.5H2O}n (2), (H4pztc=pyrazine-2,3,5,6-tetracarboxylic acid, bpe=1,2-bis(4-pyridyl)ethane, 4,4'-bpy=4,4'-bipyridine), have been prepared by modifying the reaction conditions at room temperature and characterized by IR, elemental analysis, thermal gravimetric analysis, fluorescence measurement and single crystal X-ray diffraction analysis. The structures of two complexes are two-dimensional (2D) networks, but H4pztc has different connection modes in 1 and 2. Complex 2 shows good luminescence properties in solid state at room temperature. Electron Paramagnetic Resonance (EPR) spectra of complex 1 is studied. |
