| Abstract: | Compounds with Organometallic Alkoxo–Indium Cages The reaction of InMe3 with PhCH2OH (molar ratio 1 : 2) at 20 °C in toluene gives the tetranuclear complex In{(PhCH2O)2InMe2}3] ( 2 ) in good yield. A further reaction under reflux conditions was not observed. However, at 160 °C in PhCH2OH a reaction could be realized, which forms an O‐centred corner‐cutted rhombic dodecahedron, (MeIn)5(OCH2Ph)8(O)] ( 3 ), under evolution of methane. This In–O skeleton can be degraded with elemental cesium to a hexa‐ and heteronuclear complex Cs{Cs(THF)}{MeIn(OCH2Ph)2]4O}] ( 4 ). 2 – 4 were characterized by IR, RE, NMR and MS techniques as well as by X‐ray analyses. According to them 2 can be described as In3+ ion, coordinated by three metalate units Me2In(OCH2Ph)2]–. 3 loses one MeIn fragment during the transfer of two electrons. Two Cs+ ions complete the new rhombic dodecahedron, at which different coordination spheres were observed. One Cs+ ion possesses additional contacts to a THF ligand and four π‐electron systems from four phenyl rings, while the THF ligand is missing in the environment of the second alkali cation. |
