摘　　要：One coordination polymer（CP） {[Mn（ADA）（Phen）]（H2O）2}n（1, H2ADA = azobenzene-4,4＇-dicarboxylic acid, Phen = 1,10-phenanthroline）, has been synthesized via hydrothermal reactions. CP 1 was characterized by elemental analyses, IR spectra, thermal behaviors, and X-ray single-crystal diffraction. In CP 1, each ADA（2-） ligand bridges two Mn（2＋） to give one-dimensional zigzag chains with the Mn···Mn separations of 17.6911 and 16.3976 A, which generates a three-dimensional supramolecular structure by means of strong π···π interaction and hydrogen bonding. It crystallizes in triclinic, space group P1, with a = 7.6200（13）, b = 9.1530（15）, c = 18.262（2） A, α = 88.467（3）o, β = 84.145（2）o, γ = 77.542（2）o, V = 1237.2（3） A3, Z = 2, C（26）H（20）MnN4O6, Mr = 539.40, Dc = 1.448 g/cm3, F（000） = 554, S = 1.018, R = 0.0531 and w R = 0.1094. In addition, natural bond orbital analysis was performed by the B3 LYP/LANL2 DZ method of Gaussian 09 Program. The fluorescence, magnetic, and electrochemical properties of 1 have been investigated.One coordination polymer（CP） {[Mn（ADA）（Phen）]（H2O）2}n（1, H2ADA = azobenzene-4,4＇-dicarboxylic acid, Phen = 1,10-phenanthroline）, has been synthesized via hydrothermal reactions.
