摘要

Two isostructural helical coordination polymers, {[Cu（dps）2（Hssa）-（H2O）2]＇3H2O}n （1） and {[Mn（dps）2（Hssa）（H2O）2]＇2H2O}n （2）, have been synthesized by the solvothermal reaction of dps and Hsssa with CuCI2 or Mn（CH3COO）2 （dps = 4,4＇-dipyridylsulfide, H3ssa -- 5- sulfosalicylic acid）. Both compounds crystallize in monoclinic, space group P21/n. In either complex, the central metal ion （Cu11 for compound 1 and MnIt for compound 2） is surrounded by one Hssa2- ligand, two coordinated aquas and three dps molecules with a N303 donor set in a distorted octahedral coordination geometry. Half of the dps is monodentate and another half acts as μ2-bridging ligands. It is through the bridging function of dps that the neighbouring metal centers are connected and a one-dimensional helical structure of compound 1 or 2 forms. Fluorescence studies indicate that compounds 1 and 2 have blue emission bands centered at 403 and 405 nm, respectively.
