A set of novel complexes of rare earth elements, M(III) = Y, La, Gd, Tb, and Dy, with the doubly-reduced dibenzo[a,e]cyclooctatetraene (DBCOT) anion has been synthesized and crystallographically characterized for the first time. Preparation of new complexes has been accomplished through the ligand-metathesis reaction of M(III) triiodides with K2(DBCOT) in THF at ambient conditions. Subsequent crystallization via slow solvent evaporation afforded single crystals of good quality. X-ray diffraction technique confirmed that all complexes are isomorphous and conform to the [M(DBCOT)(THF)4][M(DBCOT)2] composition. In their crystal structures, the monoanionic double-decker sandwiches, [M(DBCOT)2], weakly interact with the cationic counterparts, [M(DBCOT)(THF)4]+. In both parts, …

Historically, the 10π-aromatic ligand, cyclooctatetraene (COT), has played a pivotal role
