| Abstract: | Three coordination polymers {Cd(pztc)(H2O)2]·(H2bpy)·3(H2O)}n (1), {Zn3(pztc)2(Hbpy)2(bpy)(H2O)4]·7H2O}n (2), and Cu6(pztc)4(Hbpy)4(bpy)2(H2O)8]·17H2O (3) (bpy=4,4'-bipyridine, H4pztc=pyrazine-2,3,5,6-tetracarboxylic acid) have been synthesized and characterized by infrared spectra, elemental analysis, thermal analysis, fluorescence and single-crystal X-ray diffraction. The hydrogen bonding interactions in complexes 1 and 3 are abundant. Complex 2 displays a 3D network and exists an interesting goldfish-like (H2O)10 cluster. Complex 3 shows 1Dherringbone chain structures, which can be linked by hydrogen bonds to form a 3Dsupramolecular structure. In addition, on excitation of 320 nm, complexes 1 and 2 emit fluorescence with emission maximum at 496 nm and 494 nm respectively. CCDC: 888444, 1; 888445, 2; 888446, 3. |
