Cycloheptatrienyl trianion: an elusive bridge in the search of exchange coupled dinuclear organolanthanide single-molecule magnets.

ABSTRACT: The preparation of η-cyclopentadienyl (η⁵-C₅R₅), η-arene (η⁶-C₆R₆), and η-cyclooctatetraenyl (η⁸-C₈R₈) bridging motifs are common in organometallic chemistry; however, the synthetic preparation of η-cycloheptatrienyl (η⁷-C₇R₇) bridging motifs has remained a synthetic challenge in 4f chemistry. To this end, we have developed a synthetic route towards a series of rare dinuclear organolanthanide inverse sandwich complexes containing the elusive η⁷-C₇H₇ bridge. Herein, we present the structures and magnetic properties of the lanthanide inverse sandwich complexes [KLn₂(C₇H₇)(N(SiMe₃)₂
