摘要：
Two complexes, [(HgLCl2)-Cl-1](n) (1) and [Hg-2(L-2)(2)Cl-4](n) (2), have been synthesized and characterized from two dipyridylamide ligands (L-1 and L-2) with mercury(II) chloride, respectively. The two complexes exist as 1D coordination polymers but exhibit different architectures with slightly adjusted 3- and 4-position of nitrogen atom in the pyridyl rings from the two ligands. In complex 1, the mercury(II) center is four-coordinated with distorted tetrahedral geometry in 1D-chain structures. In complex 2, the mercury(II) center is five-coordinated with distorted square pyramidal geometry in the 1D-looped structures. The thermal stabilities and vapor adsorption properties of the two complexes were investigated as well.
