The influence of bromide and iodide-halides on (H2-2AMP)PbX4 (X = Br and I) compounds, focusing on their structural, chemical, and optical characteristics was investigated in this study. Synthesized via a reflux method under a nitrogen atmosphere, the compounds were analyzed using FT-IR spectroscopy and XRD analysis. Despite differing halides, both compounds share an orthorhombic crystal structure, with distinct cell parameters and bond lengths. The UV-Vis analysis reveals significant tuning of the cut edge within the visible range, offering insights into their potential of the materials in optoelectronic applications.
