The synthesis and characterization of two bimetallic, cationic low‐valent gallium–cryptand[2.2.2] complexes is reported. The reaction of cryptand[2.2.2] with Ga 2 Cl 4 gave two different cations, [Ga 3 Cl 4 (crypt‐222)] + ( 1 ) or [Ga 2 Cl 2 (crypt‐222)] 2+ ( 2 ), depending on whether or not trimethylsilyl triflate (Me 3 SiOTf) was added as a co‐reagent. Complexes 1 and 2 are the first examples of bimetallic cryptand[2.2.2] complexes, as well as the first low‐valent gallium–cryptand[2.2.2] complexes. Computational methods were used to evaluate the bonding in the gallium cores.
