Sn(HPO)(TPyP)∙6HO (), an ionic tin porphyrin complex, was synthesized from the reaction of [Sn(OH)TPyP] () with a dilute aqueous solution of a polyprotic acid (HPO). Complex was fully characterized using various spectroscopic methods, such as X-ray single-crystal crystallography, H NMR spectroscopy, elemental analysis, FTIR spectroscopy, UV-vis spectroscopy, emission spectroscopy, EIS mass spectrometry, PXRD, and TGA analysis. The crystal structure of reveals that the intermolecular hydrogen bonds between the peripheral pyridinium groups and the axially coordinated dihydrogen phosphate ligands are the main driving force for the supramolecular assembly. Simultaneously, the overall association of these chains in leads to an open framework with porous channels. The photocatalytic degradation efficiency of methyl orange dye and tetracycline antibiotic by was 83% within 75 min (rate constant = 0.023 min) and 75% within 60 min (rate constant = 0.018 min), respectively. The self-assembly of resulted in a nanostructure with a huge surface area, elevated thermodynamic stability, interesting surface morphology, and excellent catalytic photodegradation performance for water pollutants, making these porphyrin-based photocatalytic systems promising for wastewater treatment.
