The asymmetric unit of title compound, [La(NO₃)₃(C₁₅H₁₅NO₂)₂(CH₃OH)], consists of two Schiff base 2-methoxy-6-[(4-methylphenyl)iminiomethyl]phenolato (HL) ligands, three independent nitrate anions and one methanol molecule 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 methoxy groups. The HL ligands are zwitterionic, with protonated imine N atoms. The coordination sphere is completed by one methanol molecule. The protonated imine N atoms are involved in intramolecular N—H⋯O hydrogen bonds with the phenoxy groups and nitrate ligands. One O atom of one nitrate group is disordered over two sites of equal occupancy.

Comment top

Schiff base ligands derived from substituted o-vanillin and aniline and their rare earth metal complexes have generated considerable attention in the past decades, due to their intriguing novel structural features (Burrows & Bailar, 1966; Zhao et al., 2007; Xian et al., 2008; Li et al., 2008) and promising applications in various fields such as catalysis, optoelectronic devices, and so on (Leadbeater & Marco, 2002; Quici et al., 2004). Interested in this field, we have been engaged in a major effort directed toward the synthesis of new analogous Schiff base derived from o-vanillin and their rare metal complexes. In few previous articles, we have reported our partial research results (Zhao et al., 2007; Xian et al., 2008; Li et al., 2008). Herein, we describe a new La(III) complex.

The single-crystal structure is shown in Fig. 1, which illustrates that the La(III) ion in this complex is eleven-coordinated by six O atoms from three nitrate radical ions, four O atoms from the Schiff bases, and one O atom from methanol. The Schiff bases are coordinated to the La(III) ion in the bidentate mode, using O atoms from methoxy groups and deprotonated phenolic hydroxyl groups. The bonds between La(III) and O atoms from phenoxy groups are 2.429 (2) and 2.482 (2) Å, which are shorter than those between La(III) and O atoms of methoxy groups [2.808 (2) and 2.964 (3) Å]. The nitrate radical anions coordinate to the La(III) with O atoms with the distances ranging from 2.574 (19) to 2.741 (3) Å, which are intermediate between the La—O(phenolic) and the La—O(methoxy) bond lengths. The La—O(methanol) bong length is only slightly longer than the La—O(phenolic). In addition, the O5 atom in a nitrate anion is disordered over two sites.

The hydrogen bonds and π···π weak non-covalent interactions give stability to the crystal structure. In each HL ligand, the proton of phenolic hydroxyl group is transferred to the imine N atom, which is involved in the formation of intramolecular hydrogen bonds. There are no classic hydrogen bonds between the adjacent molecules. π···π interactions exist in the crystal between symmetry-related molecules.

Experimental top

Reagents and solvents are commercially available and were not purified before use. The Schiff base ligand 2-[(4-methylphenyl)iminomethyl]-6-methoxy-phenol was synthesized by condensation of o-vanillin and p-methylaniline. The title complex was obtained by adding La(NO₃)₃ (1 mmol, dissolved in 20 ml methanol) to N-salicylidene-p-toluidine (2 mmol) in methanol. The mixture was stirred for 8 h at room temperature. The resulting solid was then filtered out and the reddish-brown solution was kept aside. Red crystals were obtained after several days.
