In article number 2005533, Matthias Wuttig and co‐workers study systematic changes of chemical bonding in lead chalcogenides (PbX, where X = Te, Se, S, O) to comprehend their properties. They discover an electron‐transfer‐driven transition from highly anharmonic, metavalent bonding in thermoelectric PbX (X = Te, Se, S) to iono‐covalent bonding in β‐PbO, highlighting the relevance of the concept of metavalent bonding for materials design.
