w The first X-ray structural characterization of bicorannulenyl dianion has been accomplished for two alkali metal salts, [Li+(THF)(4)](2)[C40H182-] (1) and [Cs+(18-crown-6)](2)[C40H182-] (2). This crystallographic study revealed the biaryl stereochemistry, geometry transformation upon acquiring two electrons, and different binding preferences of Li+ vs Cs+ ions in the solid-state products.
