(a) Crystal structure of phlogopite-1M, represented with SiO4, AlO4 and MgO6 coordination polyhedra. The tetrahedral and octahedral sheets are labelled as T and O, respectively, whereas the interlayer is named i. (b) Details of the structure of an optimized TOT + i (001) monolayer of Phl, where the basal, apical and hydroxyl oxygen atoms are labelled Ob, Oa and Oh, respectively. The cationic sites in the O sheet are marked with the labels M1–M6. (c) Polyhedral representation of the (001) surface of the Phl monolayer. The blue dashed lines in the panels represent the 3D or 2D unit cell of the mineral, and the black dashed lines show the K⋯Ob interactions.
