• Thickness-dependent growth of ultrathin PbBr2 films on Ag(1 1 1) was systematically investigated. • Characteristic LEED patterns originate from multidirectional domains of a “ripple-like” surface structure. • PbBr2 and metallic Pb coexist at intermediate thicknesses, as revealed by XPS. • PbBr2-derived surface structures are thermally stable up to 150 °C. • Annealing at 200 °C induces partial decomposition and reconstruction into Pb rich surfaces.
