Bis{2-methoxy-6-[(4-methylphenyl)iminiomethyl]phenolato-κ2O1,O2}tris(nitrato-κ2O,O′)methanolsamarium(III)

The asymmetric unit of the title compound, [Sm(NO3)3(C15H15NO2)2(CH3OH)], 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 chelat...
