The new Si24 allotrope has an open-framework structure comprised of 5-, 6- and 8-membered sp3-bonded silicon rings. Small atoms like sodium (yellow) and lithium (green), and potentially molecules like water, can readily diffuse through these channels, with potential applications spanning electrical energy storage and molecular-scale filtering.

Si24 was synthesized by extracting sodium atoms from Na4Si24using a thermal diffusion process. Na atoms (yellow) can diffuse through the large channels in the structure, resulting in a completely sodium-free lattice. Image credit: Timothy Strobel.
