Analysis of the materials on the convex hull is fairly straightforward. WCl 2 doesn't have any neighbors within the mutual information structural cutoff distances. Additionally tungsten and chlorine are relatively rare within the dataset. YB 4 W is structurally unique with layers of yttrium and tungsten separated by a boron network. It is also space group 1 or in other words the least symmetric and is the only compound in the dataset with this space group number. Li 2 O has an anti-fluorite structure and despite being an oxide is the only compound containing lithium in significant quantity.
