Gallium hydride stabilized by the base quinonuclidine reacts with acetone under addition of the Ga‐H function to the carbon–oxygen double bond yielding (HGa) 5 (OiPr) 8 O ( 1 ) as isolable compound. (HGa) 5 (OiPr) 8 O may be formally split in to four entities of HGa(O i Pr) 2 and one entity HGaO. The inner atomic skeleton of 1 is a novel Ga 5 O 9 heterocluster with gallium atoms occupying the corners of a distorted trigonal bi‐pyramid, an oxygen atom in the center and the remaining alcoholate oxygen atoms bridging eight of the nine edges of the bi‐pyramid (X‐ray diffraction analysis). Potassium indium alkoxide KIn(OtBu) 4 has been used to synthesize several new compounds like In 4 (OtBu) 8 (C 5 H 4 ) 2 ( 2 ), (py) 2 CuIn(OtBu) 4 ( 3 ), and [CuIn(OtBu) 4 ] 2 ( 4 ) by reaction with TiCl 2 cp 2 ( 2 ) and CuCl ( 3 , 4 ). All compounds were characterized by spectroscopic means and by X‐ray structure analyses revealing novel polycyclic structures.
