摘要：

Two new Cd-II coordination frameworks with the semirigid asymmetric ligand L, [Cd2L2(p-bdc)](n) (1) and [CdL(btec)(0.25)](n) (2) (L = 4-[(2-(pyridine-2-yl)-1H-imidazol-1-yl)methyl]benzoic acid, p-bdc = 1,4-benzenedicarboxylic acid, btec = 1,2,4,5-benzenetetracarboxylic acid), were synthesized hydrothermally. In complex 1, p-bdc ligands link [Cd-2(COO)(4)N-4] double-chains to give a 2D network. In complex 2, two Cd-II ions and two ligands L form a 26-membered ring, which is further connected by btec ligands in chelate-monodentate coordination modes to construct a 2D polymeric sheet. In addition, the photoluminescence properties of the free ligand L and the two complexes were studied in the solid state at room temperature
