Abstract: | Reaction of divalent Sm(OAr)2(THF)3 (Ar = C6H2‐tert‐Bu3‐2,4,6; THF = tetrahydrofuran) with one equivalent of azobenzene in THF and crystallization of the product in diethyl ether afforded the title complex (ArO)2(THF)2Sm(η2‐N2Ph2)·Et2O in good yield. In the complex, the N? N bond length for the azobenzene species is lengthened. The two Sm? N bonds are equivalent, and their bond lengths are intermediate between the donor bond and the single bond.
