The synthesis,structural characterization and thermal behavior of a novel one-dimensional manganese (Ⅱ) complex of formula [Mn(1,5-nds)(Him)4]n [1,5-nds=naphthalene-1,5-disulfonate,Him=imidazole] is reported.The complex crystallizes in the triclinic system,space group P1,with a=0.835 42(13) nm,b=0.983 45(18) nm,c= 0.987 42(19) nm,α=60.523 0(10)°,β=97.748(2)°,γ=87.189(2)° and Z=2.The 1,5-nds ligand assumes the μ2 coordination mode and interlinks Mn(Ⅱ) ions into infinite one-dimensional chain structure along [111] direction,with the adjacent Mn…Mn distance being 1.144 99(12) nm.The chains are assembled into a three-dimensional supramolecular architecture via hydrogen bonds and C-H…π interactions.IR spectra and thermal analysis data are in agreement with the crystal structure.
