Abstract

Moonlight metal: The valence-precise compound Rb₄Sn ₅P₄Se₂₀ (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.
