Crystals of the title compound were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb. Lanthanum (III) chloride hexahydrate (143 mg, 0.4 mmol), phen (79.2 mg, 0.4 mmol), phenoxyacetic acid (182.6 mg, 1.2 mmol) and distilled water (6 g) were placed into the bomb and sealed. The bomb was then heated under autogenous pressure for 7 d at 433 K and allowed to cool at room temperature for 24 h. Upon opening the bomb, a clear colorless solution was decanted from small colorless crystals. These crystals were washed with distilled water followed by ethanol, and allowed to air-dry at room temperature.
H atoms were positioned geometrically, with C—H = 0.93 and 0.97 Å for aromatic and methylene H atoms, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).
There has been great interest in the design and synthesis of supramolecular metal organic frameworks with organic ligands and rare earth metals exhibiting novel properties such as optical, electronic, magnetic and biological (Swiegers & Malefetse, 2002; Johnson & Raymond, 2001; Hof et al., 2002; Tsukube & Shinoda, 2002; Zhang et al., 2005). In the synthesis of supramolecular metal organic frameworks by design, the assembly of molecular units in predefined arrangements is a key goal (Desiraju, 1997; Braga et al., 1998). Directional intermolecular interactions are the primary tools in achieving this goal and hydrogen bonding is currently the best tool amongst them (Zaworotko, 1997; Braga & Grepioni, 2000). These compounds are usually prepared by the reaction of rare-earth metal ions with bi- or multidentate ligands (Kay et al., 1972; Ma et al., 1999; Mao et al., 1998). 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). It has an inversion centre between the two LaIII ions, in which they are bridged by the two terdentate and the two bidentate carboxylate groups. Each La atom is seven-coordinated by the two N atoms of 1,10-phenanthroline (phen) ligand and the five O atoms of 2-pyridyloxyacetic acid ligands (Table 1). The La—O and La—N bonds are in the range of [2.457 (3)–2.887 (3) Å] and [2.739 (3)–2.769 (3) Å], respectively.
In the crystal structure, intermolecular C—H···O hydrogen bonds (Table 2) lead to a supramolecular network structure (Fig. 2), in which they may be effective in the stabilization of the structure.

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. |

There has been great interest in the design and synthesis of supramolecular metal organic frameworks with organic ligands and rare earth metals exhibiting novel properties such as optical, electronic, magnetic and biological (Swiegers & Malefetse, 2002; Johnson & Raymond, 2001; Hof et al., 2002; Tsukube & Shinoda, 2002; Zhang et al., 2005). In the synthesis of supramolecular metal organic frameworks by design, the assembly of molecular units in predefined arrangements is a key goal (Desiraju, 1997; Braga et al., 1998). Directional intermolecular interactions are the primary tools in achieving this goal and hydrogen bonding is currently the best tool amongst them (Zaworotko, 1997; Braga & Grepioni, 2000). These compounds are usually prepared by the reaction of rare-earth metal ions with bi- or multidentate ligands (Kay et al., 1972; Ma et al., 1999; Mao et al., 1998). 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). It has an inversion centre between the two LaIII ions, in which they are bridged by the two terdentate and the two bidentate carboxylate groups. Each La atom is seven-coordinated by the two N atoms of 1,10-phenanthroline (phen) ligand and the five O atoms of 2-pyridyloxyacetic acid ligands (Table 1). The La—O and La—N bonds are in the range of [2.457 (3)–2.887 (3) Å] and [2.739 (3)–2.769 (3) Å], respectively.
In the crystal structure, intermolecular C—H···O hydrogen bonds (Table 2) lead to a supramolecular network structure (Fig. 2), in which they may be effective in the stabilization of the structure.
