Cd (Ⅱ) fluorescence complex constructed with ionic ligands and Hirshfeld surface analysis
Using 4-carboxyl-1-(3-carboxybenzyl) pyridinium chloride (H

through ambient temperature volatilization. The structure and properties of the complex

were characterized by single crystal X-ray diffraction, Hirshfeld surface and two-dimensional fingerprint, powder X-ray diffraction, thermogravimetric analysis, and solid-state fluorescence. The study showed that the complex crystallized in the monocl

metal centers connected by fully deprotonated ligands, forming two mirror-symmetrical "S" shaped double-chain structures. The rich intermolecular forces such as H···H and O···H helped the complex form a stable three-dimensional supramolecular structure. Thermogravimetric analysis showed that the complex had a good thermal stability. In addition, room temperature fluorescence testing showed that the complex
1
also had a good fluorescence emission ability.
