The reaction of Ga 2 X 4 · 2 dioxane with four equivalents of (Me 3 Si) 3 SiLi(thf) 3 (= hypersilyllithium) affords for X = Br a 1,3,2,4‐disiladigalletane together with tetrahedral hypersilylgallium(I). For X = Cl an anionic 1,2,3,4‐silatrigalletanate, a four‐membered heterocycle with a Ga 3 unit, is isolated. These primary examples of gallium/group‐14 heterocycles have been investigated by NMR spectroscopy as well as by X‐ray single‐crystal structure analysis. In addition, the synthesis and structure of bis(hypersilyl)gallium chloride is described. This monomeric molecule has a nearly T‐shaped Si 2 GaCl framework.
