Materials discovery enables both realization and understanding of new, exotic, physical phenomena. An emerging approach to the discovery of novel phases is high‐pressure synthesis within diamond anvil cells, thereby enabling in situ monitoring of phase formation. Now, the discovery via high‐pressure synthesis of the first intermetallic compound in the Cu‐Pb system, Cu 3 Pb is reported. Cu 3 Pb is notably the first structurally characterized mid‐ to late‐first‐row transition‐metal plumbide. The structure of Cu 3 Pb can be envisioned as a direct mixture of the two elemental lattices. From this new framework, we gain insight into the structure as a function of pressure and hypothesize that the high‐pressure polymorph of lead is a possible prerequisite for the formation of Cu 3 Pb. Crucially, electronic structure computations reveal band crossings near the Fermi level, suggesting that chemically doped Cu 3 Pb could be a topologically nontrivial material.
