A Zn(II)-based 1D Coordination Polymer with Adsorption Properties and Hirshfeld Surface Analysis

A polymeric coordination compound [Zn2(PABA)2(H2O)2Cl2]n (1) (where PABA is para-aminobenzoic acid) has been synthesized and characterized. We examined and explicated the porosity of the compound and employed a low-temperature nitrogen adsorption technique at 77 kelvins. Throughout the experiments, the nitrogen partial pressure ranged from 0.005 to 0.995 P/P0, aligning with the nitrogen adsorption and desorption curves. The surface area (SBET) was found to be 1945.72 m2/g with a micropore area of 361.56 m2/g that ensures the material’s ability to effectively adsorb small molecules. The nitrogen adsorption behavior on this compound is not only facilitates a deeper comprehension of its textural and structural attributes but also unveils potential applications, especially in pharmaceutical domains. Additionally, Hirschfeld surface analysis was performed, yielding interatomic interaction percentages on the Hirschfeld surface.
