Bis{2-methoxy-6-[(4-methylphenyl)iminiomethyl]phenolato-κ(2) O (1),O (2)}tris(nitrato-κ(2) O,O′)methanolsamarium(III)
The asymmetric unit of the title compound, [Sm(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], contains two Schiff base 2-methoxy-6-[(4-methylphenyl)iminiomethyl]phenolate (HL) ligands, three nitrate ions and one methanol molecule that binds to the nine-coordinate samarium(III) ion via its O atoms. Th...

Sumario: | The asymmetric unit of the title compound, [Sm(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], contains two Schiff base 2-methoxy-6-[(4-methylphenyl)iminiomethyl]phenolate (HL) ligands, three nitrate ions and one methanol molecule that binds to the nine-coordinate samarium(III) ion via its O atoms. The HL ligands chelate with a strong Sm—O(deprotonated phenolic) bond and a weak Sm—O(methoxy) contact. The latter can be interpreted as the apices of the bicapped square-antiprismatic Sm(III)O(9) polyhedron. The Schiff base ligands are in a zwitterionic state with the phenolic H atom transferred to the imine N atom. O—H⋯O, O—H⋯N and N—H⋯O hydrogen bonds lend stability to the structure. One O atom of one nitrate group is equally disordered over two positions. |
