The tetraalkyldigallium(II) compound R 2 Ga–Ga R 2 ( 1 ) [ R = CH(SiMe 3 ) 2 ] reacted with amino and hydroxo functionalized carboxylic acids by retention of the Ga–Ga bond and release of CH 2 (SiMe 3 ) 2 . New heterocyclic or cage‐like compounds were formed with three, two, or six Ga–Ga bonds in a single molecule. The latter dodecagallium compounds encapsulated THF or dioxane molecules in their molecular cavities (carcerands), the other compounds have up to six THF molecules coordinated by N–H ··· O hydrogen bonds.
