Pressure-induced charge transfer from one element to another in three hexagonal perovskites represent the first such transitions involving 4d or 5d metals, and double the total number ever observed. Electrons can be “squeezed” from the 6s shell of Bi into the 4d or 5d shells of Ru/Ir, resulting in a 1 % volume reduction that becomes favorable above 5 GPa.
