Crystals of the title compound (I) were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb, which was then sealed. Samarium (III) nitrate hexahydrate (218.5 mg, 0.5 mmol), phen (198 mg, 1 mmol), anilinoacetic acid (146.2 mg, 1 mmol), ammonia (0.5 mol/l, 2 ml) and distilled water (6 g) were placed into the bomb and sealed. The bomb was then heated under autogenous pressure up to 423 K over the course of 7 d and allowed to cool at room temperature for 24 h. Upon opening the bomb, a clear colourless 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.
The H atoms were positioned geometrically, with N— H = 0.86 Å (for NH) and C—H = 0.93 - 0.97 Å (for CH), and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C, N), where x = 1.2 for aromatic H atoms and x = 1.5 for all other H atoms.
In recent years, there has been great interest in the synthesis of metal organic frameworks (MOFs) with organic ligands and rare earth metals because of their novel structures, fascinating properties and important roles in special materials having optical, electronic, magnetic and biological importance potential applications (Daiguebonne et al., 2000; Farrugia et al., 2000; Tsukube & Shinoda, 2002; Zhang et al., 2005). These compounds are usually prepared by the reaction of rare-earth metal ions with bi- or multidentate ligands (Starynowicz, 1991, 1993; Kay et al., 1972; Ma et al., 1999; Zeng et al., 2000; 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). The title compound, [Sm2(C8H8NO2)6(C12H8N2)2]n, which are the metal organic framework synthesized by the anilinoacetate ligand and the rare earth metal Sm, are bridged by two terdentate, two bidentate and four mondentate carboxyl groups with an inversion centre between the two SmIII ions. Each Sm atom is nine-coordinated by two N atoms of 1,10-phenanthroline (phen) ligand and seven O atoms of four anilinoacetate ligands (Table 1). The Sm—O bond lengths are in the range 2.414 (3) to 2.822 (4) Å. The Sm—N bond lengths are in the range 2.710 (4) to 2.728 (4) Å. In the crystal structure, N—H···O, C—H···N and C—H···O hydrogen bonds (Fig. 2 and Table 2) seem to be effective in the stabilization of the structure, resulting in the formation of a supramolecular network 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. |

In recent years, there has been great interest in the synthesis of metal organic frameworks (MOFs) with organic ligands and rare earth metals because of their novel structures, fascinating properties and important roles in special materials having optical, electronic, magnetic and biological importance potential applications (Daiguebonne et al., 2000; Farrugia et al., 2000; Tsukube & Shinoda, 2002; Zhang et al., 2005). These compounds are usually prepared by the reaction of rare-earth metal ions with bi- or multidentate ligands (Starynowicz, 1991, 1993; Kay et al., 1972; Ma et al., 1999; Zeng et al., 2000; 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). The title compound, [Sm2(C8H8NO2)6(C12H8N2)2]n, which are the metal organic framework synthesized by the anilinoacetate ligand and the rare earth metal Sm, are bridged by two terdentate, two bidentate and four mondentate carboxyl groups with an inversion centre between the two SmIII ions. Each Sm atom is nine-coordinated by two N atoms of 1,10-phenanthroline (phen) ligand and seven O atoms of four anilinoacetate ligands (Table 1). The Sm—O bond lengths are in the range 2.414 (3) to 2.822 (4) Å. The Sm—N bond lengths are in the range 2.710 (4) to 2.728 (4) Å. In the crystal structure, N—H···O, C—H···N and C—H···O hydrogen bonds (Fig. 2 and Table 2) seem to be effective in the stabilization of the structure, resulting in the formation of a supramolecular network structure.
