title: Bis(μ-2-{bis-[(2-oxidobenzyl-idene)amino]-meth-yl}phenolato)bis-[(tetra-hydro-furan)-samarium(III)] tetra-hydro-furan disolvate.
abstract: 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.
