a, The 3D diamond-type superlattice in ICF-5 CuInS-Na. Unconnected spheres are Na+ sites. b, The rings formed by six T5 clusters are present in the 3D interpenetrating diamond-type superlattice in ICF-17. c, T2 clusters in ICF-21 InSe-Na are connected into a non-interpenetrating diamond-type lattice. Unconnected spheres are Na+ sites. d, The 3D diamond-type superlattice with core-less T4 clusters (In16S3216-) in ICF-22 InS-Li. Only one sublattice is shown here for clarity. e, The 3D framework of ICF-24 with 20-ring channels. f, The 3D framework of ICF-25 with 16-ring channels.
