摘　　要：The two title complexes, [Cd{3,5-（NO2）2sal}（2,2′-bipy）]n 1 and [Mn{3,5- （NO2）2sal}（2,2′-bipy）]n 2 （3,5-（NO2）2sal = 3,5-dinitrosalicylate, 2,2＇-bipy = 2,2′-bipyridine）, were synthesized by the hydrothermal reaction and structurally characterized. Complex 1 crystallizes in triclinic, space group P1, a = 5.581（4）, b = 12.071（8）, c = 12.88（1）A, α= 92.10（3）,β= 96.73（3）, γ = 102.02（2）°, C17H10N407Cd, Mr = 494.69, V= 841（1）A3, Z = 2, Dc = 1.954 g/cm3, F（000） = 488, μ= 1.353 mm^-1, R = 0.0248 and wR = 0.0761. Complex 2 crystallizes in monoclinic with space group P21/c, a = 8.604（3）, b = 23.88（1）, c = 8.894（3） A, β = 102.45（1）°, C17H10N407Mn, Mr = 437.23, V= 1785（1） A3, Z=.4, Dc = 1.627 g/cm3, F（000） = 884, μ = 0.791 mm^-1, R = 0.0471 and wR = 0.1250. Complex 1 possesses an infinite 1D polymeric chain structure consisting of the repeated basic four-membered ring units （Cd2O2） and eight-membered ring units （CdOCO）2. Compound 2displays a linear 1D chain through Mn（Ⅱ） atoms and bridging carboxylate groups of 3,5-dinitrosalicylic acid ligands with the Mn…Mn separation of 4.472（2）A. The fluorescence properties and cyclic voltammetric behaviors of the complexes are also reported.The two title complexes, [Cd{3,5-（NO2）2sal}（2,2′-bipy）]n 1 and [Mn{3,5- （NO2）2sal}（2,2′-bipy）]n 2 （3,5-（NO2）2sal = 3,5-dinitrosalicylate, 2,2＇-bipy = 2,2′-bipyridine）, were synthesized by the hydrothermal reaction and structurally characterized.
