Whereas optical BICs have been realized in photonic systems, achieving electronic bound states embedded in a metallic background remains an ongoing challenge. In this study, we used scanning tunneling microscopy to identify two defect-induced electronic states that remain localized within the metallic continuum of Pd\n                    <jats:sub>5<\/jats:sub>\n                    AlI\n                    <jats:sub>2<\/jats:sub>\n                    , a two-dimensional van der Waals metal.
