The mono‐ and di‐chloroform solvates of [Au 2 (μ‐1,2‐bis(diphenylarsino)ethane) 2 ](AsF 6 ) 2 undergo single‐crystal‐to‐single‐crystal transformations that result in gain (over 12 hours) or slow loss (over five years) of only one chloroform molecule. The change in solvation results in changes in the structure and luminescence of the digold cation. The cation consists of a pair of slightly bent As‐Au‐As units that are connected through the two bridging dpae ligands and by aurophilic interactions with Au⋅⋅⋅Au contacts of 3.05152(15) Å in the disolvate or 2.9570(5) Å in the monosolvate.
