Two 1D chain metal-organic framework complexes, {Co[(C_(10)H_5N_3O_5)-(H_2O)_2·H_2O]}n(1) and {Cd[(C_(10)H_5N_3O_5)(H_2O)_2]}_n(2), based on a T-shaped tripodal ligand 4-(4,5-dicarboxy- 1H-imidazol-2-yl) pyridine 1-oxide(H3DCImP y O) have been reacted under hydrothermal conditions, and were characterized by single-crystal X-ray structure analysis, fluorescent analysis and thermal gravimetric analysis. According to single-crystal X-ray determination, complex 1 crystallizes in the monoclinic system, space group P21/n with a = 9.4930(13), b = 13.2024(18), c = 10.5203(14) ?, β = 98.402(2)°, Z = 4, V = 1304.4(3) ?3; and complex 2 crystallizes in the monoclinic system, space group C2/c with a = 13.557(3), b = 13.568(3), c = 6.7804(13) ?, β = 105.095(2)°, Z = 4 and V = 1204.2(4) ?3. Fluorescent analysis of complex 2 showed an intense emission band at 466 nm when the exciting radiation was set at 360 nm. Dielectric constants of complexes 1 and 2 were measured at different frequencies with temperature variation.
