Reactions of Trimethylindium with Primary Alcohols InMe 3 was treated with EtOH in boiling THF while n PrOH, n BuOH and i BuOH were reacted with InMe 3 in boiling toluene. With EtOH the decanuclear complex [(MeIn) 10 (O) 2 (OEt) 12 (OH) 4 ]·2THF ( 1 ) was isolated. n PrOH, n BuOH and i BuOH lead to the pentanuclear complexes [(MeIn) 5 (O)(OR) 8 ] ( 2 – 4 ). 1 – 4 were characterized by NMR and vibrational spectroscopy as well as by X‐ray structure determinations. According to this 1 consits of two O‐centered single‐decapitated rhombic dodecahedrons In 5 O 9 , bridged by four μ 3 ‐OH functions, which are part of the In 5 O 9 cages. The two THF molecules are linked by hydrogen bonding to OH groups. In 2 – 4 always O‐centered single‐decapitated rhombic dodecahedrons In 5 O 9 are present. The structures of 2 and 3 show disorder of the In 5 O 6 cages, in which the sixth empty In position of the rhombic dodecahedron is partly occupied by one of the other five In positions. Therefore, the occupation parameter of every In position is 5/6. In 4 the empty sixth position is occupied partly by the opposite In atom In3. This means an occupation parameter of 0.5 of In3.
