Fragment of the DFT-optimized structures of mimetite-2M, -M and -H (projection along the [110]hex, chex-axis vertical). ELF isosurfaces are reported in yellow and light blue for ELF = 0.96 and ELF = 0.90, respectively. As tetrahedra are shown in light green, Cl atoms in green. Dark-grey and purple spheres represent Pb atoms residing at Pb2 and Pb1 crystallographic sites, respectively. |
