Foreshadowing a new selenium modification …? Upon treatment of red, amorphous selenium with the silver salts of two large weakly coordinating anions (WCA), the thermodynamically driven formation of [Ag 2 Se 12 ] 2+ occurred. The structure of the dication is an unprecedented D 3 d ‐symmetric 14‐vertex cage built from six six‐membered rings in a boat conformation that includes a weak argentophilic Ag–Ag bond.
