Conversely, the exploration was believed to be nearly complete for the ID-free systems. Taking this into account, the stark increase in the number of within-6-kcal/mol structures from bare MgCl2 to 19MgCl2/4TiCl4 is a result of adding another species plus the low coverage enabling many adsorption sites available for each TiCl4. Increasing the surface coverage to 19MgCl2/9TiCl4 caused the number of structures within 6 kcal/mol to become the lowest. This is due to the combination of the high surface coverage and limited adsorption modes of TiCl4 that led to a severe restriction in the nanoplate shape. In the same coverage, even though the ID-containing systems were less explored, the number of structures within 6 kcal/mol was already larger than that for 19MgCl2/9TiCl4, reflecting various patterns of coadsorption between TiCl4 and ID. Furthermore, DEP has more adsorption modes than DE, which afforded far the larger number of structures within 6 kcal/mol. The prevalence of the 90° edge motif discussed in the previous section seems to be another factor in the reduced structural variety for DE.
