Crystals of the title compound were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb, which was then sealed. Lanthanum trinitrate hexahydrate (324.9 mg, 1 mmol), 4,4'-bipyridyl (312 mg, 2 mmol), and distilled water (10 g) were placed into the bomb and sealed. The bomb was then heated under autogenous pressure for 7 d at 453 K and allowed to cool at room temperature for 24 h. Upon opening the bomb, a clear colorless solution was decanted from small colourless crystals. These crystals were washed with distilled water followed by ethanol, and allowed to air-dry at room temperature.
H atoms of water were located from difference Fourier syntheses and refined with restraints to the O—H distances and the H—O—H angles. The remaining H atoms were positioned geometrically, with C—H = 0.93 Å, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).
Molecular magnetic compounds, such as molecular ferro- and ferrimagnets, organic magnets, single-molecule magnets and high-spin molecules, have recently attracted attention (Miller & Drillon, 2001a,b, 2002). Owing to Lanthanide metals unique physical and chemical properties, Lanthanide complexes play an important role in special materials having optical, electronic, magnetic and biological importance (Benelli et al., 1992; Daiguebonne et al., 2000; Farrugia et al., 2000). More importantly, since the removal of lanthanides from radioactive highlevel liquid waste (HLLW) has been shown to improve the transmutation of long-lived transuranic elements to shortlived or even stable nuclides (Modolo & Odoj, 1998), the coordination chemistry of the 4f metals continues to attract interest. We report herein the crystal structure of the title compound, (I).
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987). The irregular nine-coordinate environment of the La atom is completed by the three O atoms of three water molecules and six O atoms of three NO3- (Table 1). The La—O bond lengths are in the range 2.357 (2) to 2.389 (2) Å for the O atoms in water molecules. The La—O bond length are in the range 2.446 (2) to 2.521 (3) Å for NO3-. The O—H···O and O—H···N hydrogen bonds link the mononuclear complex into a supramolecular network structure (Fig. 2).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Molecular magnetic compounds, such as molecular ferro- and ferrimagnets, organic magnets, single-molecule magnets and high-spin molecules, have recently attracted attention (Miller & Drillon, 2001a,b, 2002). Owing to Lanthanide metals unique physical and chemical properties, Lanthanide complexes play an important role in special materials having optical, electronic, magnetic and biological importance (Benelli et al., 1992; Daiguebonne et al., 2000; Farrugia et al., 2000). More importantly, since the removal of lanthanides from radioactive highlevel liquid waste (HLLW) has been shown to improve the transmutation of long-lived transuranic elements to shortlived or even stable nuclides (Modolo & Odoj, 1998), the coordination chemistry of the 4f metals continues to attract interest. We report herein the crystal structure of the title compound, (I).
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987). The irregular nine-coordinate environment of the La atom is completed by the three O atoms of three water molecules and six O atoms of three NO3- (Table 1). The La—O bond lengths are in the range 2.357 (2) to 2.389 (2) Å for the O atoms in water molecules. The La—O bond length are in the range 2.446 (2) to 2.521 (3) Å for NO3-. The O—H···O and O—H···N hydrogen bonds link the mononuclear complex into a supramolecular network structure (Fig. 2).
