The first crystalline iodocarbenium iodide 1 has an almost linear CII sequence, as revealed by the X‐ray structure analysis. Thus 1 contains a new hypervalent three‐center, four‐electron bonding system and marks a characteristic point on the general reaction coordinate of the polar α‐di‐halogen elimination.
