•1 is a discrete mononuclear molecule.•2 consists of one-dimensional left-helix and right-helix chains.•Two new coordinated modes of H2PIDC- are reported for the first time.•Their fluorescence properties have been investigated.
Two new supramolecular compounds, [Cd(H2PIDC)2(H2O)]·H2O (1) and {[Cd(H2PIDC)2(H2O)]·2H2O}n (2) (H3PIDC = 2-(pyridine-2-yl)-1H-imidazole-4,5-dicarboxylic acid), have been synthesized under hydrothermal conditions and structurally characterized by single-crystal X-ray diffraction. Compound 1 contains discrete mononuclear structure, and compound 2 consists of one-dimensional left- and right-helix chains. Both are constructed into high-dimensional supramolecular frameworks by strong non-covalent hydrogen bonding and π⋯π stacking interactions. In addition, they were characterized by IR and elemental analysis, and their fluorescence properties in the solid state at room temperature have also been investigated.
Graphical abstractTwo new cadmium coordination compounds were synthesized through hydrothermal reaction between cadmium salt and H3PIDC. 1 contains discrete mononuclear structure, and 2 consists of one-dimensional left- and right-helix chains. Their fluorescence properties in the solid state at room temperature have also been investigated.Figure optionsDownload full-size imageDownload as PowerPoint slide
