We used our results set as a platform to effectively explore the established design principles commonly used in the community to identify electrides. We discuss the element composition with respect to cations, anions and overall electronegativity and find a surprising breadth of chemistries on display. The heuristic rule of necessitating strongly donating cations does apply to many cases but not all, see 𝑁𝑏 2 𝑃 3 𝑂 12 for example (Figure of the SI). Similarly, we see a strong presence of transitional metals and variable oxidation state cations in our candidates, see for example 𝐶𝑟𝑆𝑖𝑇𝑒 3 (Figure in the SI), which have been previously eschewed in screening studies looking for electrides. That said, we do conclude that chemical substitution working from known electrides is likely a fruitful avenue of research for future studies, given the repeating occurrence of identical structures in spite of our screening methods omission of structural factors. We also find that the anions can and are often surprisingly electronegative, with nitrides being a minority of candidates unlike the case for confirmed electrides in experiment. This observation imparts great hope for further discovery of more air and water stable electrides like 𝐶𝑎 12 𝐴𝑙 14 𝑂 32 that can find use in catalysis or industrial applications. To this end, we recommend the analogous 𝐵𝑎 3 𝐴𝑙𝑂 4 as a promising candidate for future study (Figure in the SI). Unfortunately, we find that average electronegativity does not seem to impart any indication of electride-like tendencies for compounds.
