In the 19MgCl2/4TiCl4 system, the {110} mononuclear species dominated, accounting for 74% of the population, while {100} dinuclear species made up 24%, and {100} mononuclear species constituted only 2%. The coverage in this composition was relatively low, leading to TiCl4's preference for adsorption on {110}. However, the likelihood of having a neighboring ligand next to the TiCl4 was also low, resulting in the absence of mono_3 species. Increasing the coverage in the 19MgCl2/9TiCl4 system resulted in the appearance of mono_3 species, which comprised 32% of the population. However, the overall population of {110} mononuclear species decreased to 52%, in cost of an increase in {100} mononuclear species to 20% due to the limited availability of adsorption sites. In ID-containing systems, the mono_3 species completely eclipsed the others, becoming more than 96% of the population for both DEP and DE. The best explanation for the increase in mononuclear species on {110}, as the three most prominent ones in Figure . In 19MgCl2/9TiCl4, species possessing one terminal
