For all the structures retrieved from the Materials Project database, we performed calculations of bonding patterns through use of the CrystalNN method. CrystalNN is a novel algorithm for determining near neighbors in crystals, introduced in 2021 and benchmarked against well-established algorithms on a set of reference crystal structures spanning elements, binaries, and ternary compounds. It has a stronger fundamental background that most of the previous algorithms, which typically rely on ad hoc heuristics. CrystalNN uses Voronoi decomposition and solid angle weights to determine the probability of various coordination environments and select the one with highest probability. It is the same algorithm that is widely used throughout the Materials Project, including for to display bonds on the web portal. CrystalNN is also the algorithm that is used for bond determination in the Materials We note here that, while CrystalNN can be reparameterized for specific classes of systems, we used it here with its default parameters, tuned and recommended for inorganic materials.
