The title complex [(η5-C5H5)(THF)Sm]2[μ-η2:η2-N2Ph2]2·2THF has been synthe- sized by the reaction of divalent (C5H5)2Sm(THF) with azobenzene and its crystal structure was determined by single-crystal X-ray diffraction analysis. It crystallizes in triclinic, space group Pī with a = 9.1617(16), b = 10.5894(17), c = 11.957(2) (A),α = 85.789(6),β = 89.395(7),γ = 82.503(6)°, V = 1147.0(3) (A)3, Z = 1, C50H62N4O4Sm2, Mr = 1083.74, Dc = 1.569 g/cm3, F(000) = 546 and ((MoKα) = 2.583 mm-1. The structure was solved by direct methods and refined by full-matrix least-squares techniques. The final R and wR are 0.0271 and 0.0637, respectively for 4963 independent reflections. Each samarium atom is involved in two single bonds (one to each N2Ph2 unit) and two donor bonds (one to each N2Ph2 unit).
