Reaction of divalent Sm(OAr) 2 (THF) 3 (Ar = C 6 H 2 ‐ tert ‐Bu 3 ‐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) 2 Sm(η 2 ‐N 2 Ph 2 )·Et 2 O in good yield. In the complex, the NN bond length for the azobenzene species is lengthened. The two SmN bonds are equivalent, and their bond lengths are intermediate between the donor bond and the single bond.
