Exploration of Intermolecular Interaction of One Silver(I) Polymer with Bis(pyrazolyl)methane Derivative: Experimental Observations, Hirshfeld Surface Analyses and Fluorescent Properties

摘要

In the superbasic medium DMSO-KOH, bis(3,3-diethoxycarbonyl-1-pyrazolyl)methane (L) was synthesized. Besides, the single crystal of L has been obtained. Meanwhile, one novel coordination polymers, [Ag(L)(NO3)] (n) (1) was successfully prepared. The single X-ray diffraction data reveal that L crystallized in the P-1 space group. Novel bis(pyrazolyl)methane derivative ligand, L acts as multidentate ligands to coordinate with Ag ion to form a six-membered boat conformation. And furthermore the nitrate groups bridge each Ag(I) to construct a zigzag chain. The fluorescent properties of the complex were examined in solution and compared with the ligand. In order to investigate the intermolecular interactions, we also studied Hirshfeld surface analysis of ligand and the complex. The Hirshfeld surface analysis reveals that the main intermolecular interactions are H center dot center dot center dot H and O center dot center dot center dot H/H center dot center dot center dot O interactions which comprise 23.9 and 33.8 % of the total Hirshfeld surface area.
