In the centrosymmetric binuclear complex of the title solvate, [Sm(2)(C(21)H(15)N(2)O(3))(2)(C(4)H(8)O)(2)]·2C(4)H(8)O, the Sm(III) is coordin-ated in a distorted monocapped octa-hedral geometry by four O atoms and two N atoms from two tridentate deprotonated 2-{bis-[(2-oxidobenzyl-idene)amino]-meth-yl}phenolate ligands and an O atom of a tetra-hydro-furan (THF) mol-ecule. The Sm⋯Sm distance in the complex is 3.8057 (4) Å. Parts of the coordinating THF mol-ecule are disordered over two sets of sites in a 0.56 (3):0.44 (3) ratio. The complex and solvent mol-ecules are linked into a three-dimensional structure via C-H⋯O hydrogen-bonding inter-actions.
在标题溶剂化物的中心对称双核配合物[Sm₂(C₂₁H₁₅N₂O₃)₂(C₄H₈O)₂]·2C₄H₈O中，Sm(III)由来自两个三齿去质子化的2-{双-[(2-氧化苄叉基)氨基]-甲基}苯酚盐配体的四个O原子和两个N原子以及一个四氢呋喃(THF)分子的一个O原子以扭曲的单帽八面体几何构型配位。配合物中Sm⋯Sm的距离为3.8057 (4) Å。配位的THF分子的部分在两组位置上无序，比例为0.56 (3):0.44 (3)。配合物和溶剂分子通过C-H⋯O氢键相互作用连接成三维结构。
