(Methanol-?O)bis-{2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato-?O,O'}tris-(nitrato-?O,O')lanthanum(III).

ABSTRACT: The asymmetric unit of title compound, [La(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], consists of two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato (HL) ligands, three independent nitrate anions and one methanol mol-ecule coordinated to La(III). The coordination environment of the La(III) ion is formed by eleven O atoms. Three bidentate nitrate anions coordinate to the La(III) ion, while two HL ligands chelate the metal center with O atoms from the phenolate and meth-oxy groups. The HL ligands are zwitterionic, with protonated imine N atoms. The coordination sphere is completed by one methanol mol-ecule. The protonated imine N atoms are involved in intra-molecular N-H?O hydrogen bonds with the phen-oxy groups and nitrate ligands. One O atom of one nitrate group is disordered over two sites of equal occupancy.
