In order to perform a study on the structural modulation in the Cd(Ⅱ)-L architecture(HL =(E)-2-[2-(3-pyridyl)ethenyl]-8-hydroxyquinoline), two different dicarboxylic acids, namely, 2-aminoterephthalic acid(H_2ATA) and 4,4￠-biphenyldicarboxylic acid(H_2BPDC), are employed as the secondary auxiliary ligands. Two new complexes [Cd_2L_2(ATA)](1) and [Cd_2L_2(BPDC)·2MeO H· 4H_2O](2) with distinct 3D frameworks were obtained. In complex 1, ligands ATA bridge the 1D Cd(Ⅱ)-L infinite chains into a 3D polymeric coordination network. Complex 2 is a 3D porous framework, in which adjacent 2D Cd(Ⅱ)-L coordination layers were linked together by the coor- dinated BPDC ligands. The variant structures of two complexes indicate that the skeleton of dicarboxylate anions plays a great role in the assembly of such different frameworks. In addition, the photoluminescent properties(fluorescent emission, lifetime, and quantum yield) of polymers 1 and 2 were also investigated in the solid state.
In order to perform a study on the structural modulation in the Cd (II) -L architecture (HL = (E) -2- [2- (3- pyridyl) ethenyl] -8-hydroxyquinoline) , 2-aminoterephthalic acid (H_2ATA) and 4,4 ¢ -biphenyldicarboxylic acid (H_2BPDC) were employed as the secondary auxiliary ligands. Two new complexes [Cd_2L_2 (ATA)] (1) and [Cd_2L_2 (BPDC) · 2MeO H · 4H 2 O] (2) with distinct 3D frameworks were obtained. In complex 1, ligands ATA bridge the 1D Cd (II) -L infinite chains into a 3D polymeric coordination network. II) -L coordination layers were linked together by the coor- dinated BPDC ligands.
