New gold(I) acetylide complexes demonstrate ligand‐scrambling in solution, resulting in a variety of stable crystalline materials representing Au⋅⋅⋅Au interactions ranging from dimers to variously kinked infinite chains with distinctive thermodynamic and luminescent properties. The simplest complex (Ar=Ph, n =1) in its scrambled form yields three distinct crystal forms. Unscrambled, it presents a unique gold‐involving helical structure, while its scrambled modification (Ar=Ph, n =2) yields perfectly linear infinite Au chains.
