Fluorenylindates: Compounds with Weak In — C Bonds In diethyl ether, fluorenyllithium reacts with indium(III) chloride to yield a lithium tetrafluorenylindate ( 1 ). Recrystallisation from THF gives [Li(THF) 4 ][In(C 13 H 9 ) 4 ] ( 2 ). If the reaction is carried out in THF, the chlorotrifluorenylindate [Li(THF) 4 ]‐[ClIn(C 13 H 9 ) 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].
