Electron-deficient compounds are chemical species that possess fewer electrons than needed for complete bonding, often leading to unique properties and reactivity patterns. These compounds typically form when central atoms have an incomplete octet or when they participate in coordinate bonding with electron-rich species. This deficiency can result in strong Lewis acid behavior, making them important in various chemical processes and applications, particularly in the formation of inorganic polymers and clusters.
