Tris[6-meth­oxy-2-(phenyl­iminiometh­yl)phenolato]-κ(4) O,O′;κO (1)-tris­(thio­cyanato-κN)samarium(III)

In the crystal structure of title compound, [Sm(NCS)(3)(C(14)H(13)NO(2))(3)], two of the zwitterionic Schiff base 6-meth­oxy-2-(phenyl­iminiometh­yl)phenolate ligands coordinate to the Sm(III) atom in a bidentate fashion via the phenolate and meth­oxy O atoms. The third Schiff base ligand is monodentate, binding only through the phenolate O atom. The coordination sphere of the eight-coordinate Sm atom is completed by the three independent thio­cyanate ions binding through their N atoms, affording a square-anti­prismatic geometry. An S atom of one of the thio­cyanate anions is disordered over two sites in a 0.85:0.15 ratio. In the phenolate ligands, the proton of the phenolic hy­droxy group transfers to the imine N atom. This proton is also involved in an intra­molecular N—H⋯O hydrogen bond that imposes a nearly planar conformation on each ligand, with dihedral angles of 1.75 (4), 3.68 (5) and 3.86 (4)° between the aromatic rings of each ligand.
