The title complex [(ArO)2(THF)Sm(μ-OH)]2?2THF (Ar = C6H2-tBu3-2,4,6) was obtained by the hydrolysis of divalent (ArO)2Sm(THF)3?THF in toluene. It crystallizes in monoclinic, space group P21/c with a = 14.7968(14), b = 18.6981(15), c = 16.8264(17) ?, β = 109.366(2)°, V = 4392.0(7) ?3, Z = 2, C88H150O10Sm2, Mr = 1668.78, Dc = 1.262 g/cm3, F(000) = 1764 and μ(MoKα) = 1.377 mm-1. The final R and wR are 0.0318 and 0.0749, respectively for 9038 observed reflections with I > 2σ(I). The complex possesses a dimeric structure with two centrosymmetric hydroxyl bridges. The samarium atom is coordinated by five oxygen atoms to form a distorted square pyramidal geometry with the average Sm–O(Ar) distance of 2.1757(19) ?. There are H-bond interactions be- tween the molecules.
