Synthesis and Structure of the First Lanthanide Complex with the Bridging, Antiaromatic 2,2'-Bipyridine Dianion:
The two-electron reduction of 2,2'-bipyridine with naphthaleneytterbium resulted in the formation of the ytterbium complex [{Yb(µ(2)-bipy)(thf)(2)}(3)] (see picture) in which antiaromatic 2,2'-bipyridine dianions bridge the ytterbium atoms in a novel µ(2)-eta(2):eta(4) fashion.
