摘要

A novel coordination polymer with 4-sulfonyl-2,6-naphthalenedicarboxylic acid (H3SNDC), {[Cd_3(NDSC)_2(H _2O)_(10)]?6H2_O}n (1), has been prepared and characterized by single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21/c with a = 12.324(4), b = 22.572(7), c = 7.1472 ?, β = 91.469(5)°, V = 1987.4(11) ?~3. In the structure, the ligands use the carboxylate groups to connect Cd(II) ions into 1D chains, and the chains are linked into 2D undulated layers through the coordination of the sulfonate groups to additional Cd(II) ions. The compound exhibits two distinct weight loss steps due to the release of all water molecules and the decomposition of the SNDC ligand, and it displays photoluminescence around 448 nm, which is blue-shifted compared with the ligand. Index Abstract: A new Cd(II) coordination polymer with 4-sulfonyl-2, 6-naphthalenedicarboxylate (NDSC) is reported. The NDSC ligand anions act as T-shape building blocks to link the metal ions into a two-dimensional coordination network resembling the brick-wall topology.
