Abstract

Moonlight metal: The valence-precise compound Rb4Sn5P4Se20 (see picture, Rb blue, Sn green, P black, Se red) is the first metallic selenophosphate. It features a new structure hybrid of “conducting” [Sn5Se8] layers and “insulating” [P2Se6] ligands. It shows the highest electrical conductivity among the chalcophosphates and an extremely low thermal conductivity of 0.44 W m−1 K−1 at room temperature.
