Crystals of the title compound were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb. Neodymium (III) chloride hexahydrate (143.4 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).
The crystal structures of tetrakis(µ-(2-pyridyloxy)acetato)bis[(1,10-phenanthroline)((2-pyridyloxy)acetato) lanthanum(III)], (II), (Liu et al., 2007a) and tetrakis(µ-(2-pyridyloxy)acetato) bis[(1,10-phenanthroline)((2-pyridyloxy)acetato)praseodymium(III)], (III), (Liu et al., 2007b) have previously been reported. The crystal structure determination of the title compound, (I), has been carried out in order to elucidate the molecular conformation and to compare it with those of (II) and (III).
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 NdIII ions, in which they are bridged by the two terdentate and the two bidentate carboxylate groups. Each Nd atom is seven-coordinated by the two N atoms of 1,10-phenanthroline (phen) ligand and the five O atoms of 2-pyridyloxy- acetic acid ligands. The Nd—O and Nd—N bonds are in the range of [2.387 (3)–2.784 (4) Å] and [2.701 (4)–2.742 (4) Å], respectively (Table 1), as in (II) and (III).
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, as in (II) and (III).
The compounds, (I), (II) and (III), are isostructural.

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. |

The crystal structures of tetrakis(µ-(2-pyridyloxy)acetato)bis[(1,10-phenanthroline)((2-pyridyloxy)acetato) lanthanum(III)], (II), (Liu et al., 2007a) and tetrakis(µ-(2-pyridyloxy)acetato) bis[(1,10-phenanthroline)((2-pyridyloxy)acetato)praseodymium(III)], (III), (Liu et al., 2007b) have previously been reported. The crystal structure determination of the title compound, (I), has been carried out in order to elucidate the molecular conformation and to compare it with those of (II) and (III).
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 NdIII ions, in which they are bridged by the two terdentate and the two bidentate carboxylate groups. Each Nd atom is seven-coordinated by the two N atoms of 1,10-phenanthroline (phen) ligand and the five O atoms of 2-pyridyloxy- acetic acid ligands. The Nd—O and Nd—N bonds are in the range of [2.387 (3)–2.784 (4) Å] and [2.701 (4)–2.742 (4) Å], respectively (Table 1), as in (II) and (III).
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, as in (II) and (III).
The compounds, (I), (II) and (III), are isostructural.
