Abstract: | Organogallium or-indium subhalides are easily available by the halogenation of the corresponding tetrahedral clusters E 4 [C(SiMe 3 ) 3 ] 4 . Three types of compounds are formed that retain the tetrahedral arrangement of In atoms or give chains with two or three Ga or In atoms connected by E─E bonds. These subhalides are suitable starting compounds for the synthesis of secondary products containing the elements in low oxidation states. Carboxylato derivatives or transition metal complexes were obtained on such a route. A persistent radical anion was formed on electron transfer to Ga 9 (CMe 3 ) 9 . |
