Here we report the synthesis of Imma-B60, an allotrope that exhibits both high electrical conductivity and plastic deformability, via the high-pressure formation of a Na4B60 precursor followed by sodium degassing. Imma-B60 exhibits a narrow bandgap (<0.2 eV) with a conductivity of ~9 × 102 S m−1, seven orders of magnitude higher than β-boron.
