    Notes: Fluorenylindates: Compounds with Weak In  -  C BondsIn diethyl ether, fluorenyllithium reacts with indium(III) chloride to yield a lithium tetrafluorenylindate (1). Recrystallisation from THF gives [Li(THF)4][In(C13H9)4] (2). If the reaction is carried out in THF, the chlorotrifluorenylindate [Li(THF)4]-[ClIn(C13H9)3] (3) is isolated. According to crystal structure analyses 2 has long and weak In  -  C bonds [224.8(5) - 230.3(5) pm], while these distances in 3 are somewhat shorter [222.9 (5) - 226.7(4) pm].

    Cäsium-Fluor-Vierringe als Strukturmotiv in Cäsium-Triorganofluorometallaten der Gruppe 13Herrn Prof. Dr. Ekkehard Fluck zum 65. Geburtstag gewidmet. (1996)

    Notes: Cesium-Fluorine Four-Membered Rings as Structural Motive in Cesium Triorganofluoro Metalates of Group 13The reactions of AlMe3, GaMe3, and InMe3 with CsF in acetonitrile furnish the corresponding trimethylfluoro metalates Cs[Me3MF] (1: M = Al, 2: M = Ga, 3: M = In). The salt-like compounds 1 - 3 were characterized by NMR, IR, and MS techniques as well as by X-ray structure analysis. Cs2F2 four-membered rings are the structure-dominating units in all three compounds. Compound 1 consists of puckered layers of weakly associated Cs2F2 rings parallel to (100), while the four-membered rings in 2 form infinite ladder-type chains. The Cs-F rings in 3 build up a heterocubane with a Cs4F4 core by ring stacking.
