Two cadmium coordination polymers constructed by varying V-shaped co-ligands:Syntheses,structures,and fluorescence properties
Based on V-shaped auxiliary ligands,two novel coordination polymers,{[Cd(bipmo)(NDC)]·1.75H2O}n(1),{[Cd(bppmo)(NDC)(H2O)]·H2O}n(2),where H2NDC=2,6-naphthalenedicarboxylic acid,bipmo=bis(4-(1H-imidazol-1-yl)phenyl)methanone,bppmo=bis(4-(pyridin-4-yl)phenyl)methanone,have been synthesized under solvothermal con-ditions.They have been characterized by single-crystal X-ray diffraction,bond valence sum calculations,IR spectra,and elemental analyses.Complex 1 shows 2-fold interpenetrating sheets of {63} topology,which interpenetrate in a 2D → 2D parallel manner.Complex 2 reveals a 3-fold interpenetrating {63} network.The results indicate that the V-shaped ligands have a great effect on the formation of the final structures.In addition,the luminescent properties of complexes 1 and 2 were investigated in detail.CCDC:2296622,1;2296623,2.
