Bis(μ-2-{bis­[(2-oxidobenzyl­idene)amino]­meth­yl}phenolato)bis­[(tetra­hydro­furan)­samarium(III)] tetra­hydro­furan disolvate

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 coordin­ated in a distorted monocapped octa­hedral geometry by four O atoms and two N atoms from two tridentate deprotonated 2-{bis­[(2-oxidobenzyl­idene)amino]­meth­yl}phenolate ligands and an O atom of a tetra­hydro­furan (THF) mol­ecule. The Sm⋯Sm distance in the complex is 3.8057 (4) Å. Parts of the coordinating THF mol­ecule are disordered over two sets of sites in a 0.56 (3):0.44 (3) ratio. The complex and solvent mol­ecules are linked into a three-dimensional structure via C—H⋯O hydrogen-bonding inter­actions.
