Crystals of the title compound were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb. Cerium (III) nitrate hexahydrate (434.1 mg, 1 mmol), phen (198 mg, 1 mmol), anilinoacetamide (290.4 mg, 2 mmol) and distilled water (12 g) were placed into the bomb and sealed. The bomb was then heated under autogenous pressure up to 453 K over the course of 7 d 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.
H1A and H6A (for NH) were located in difference syntheses and refined isotropically [N—H = 0.80 (2) and 0.84 (5) Å, Uiso(H) = 0.073 (19) and 0.09 (2) Å2]. The remaining H atoms were positioned geometrically, with N—H = 0.86 Å (for NH) and 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,N).
The crystal structures of catena-Poly[hexakis(µ2-anilinoacetamide-O,N)bis- (1,10-phenanthroline-N,N')disamarium(III)], (II), and catena-Poly[hexakis- (µ2-anilinoacetamide-O,N)bis(1,10-phenanthroline-N,N')dipraseodymium(III)], (III), have previously been reported (Liu & Zhu, 2007a,b). 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). We report herein the crystal structure of (I).
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles (Table 1) are within normal ranges (Allen et al., 1987). It has an inversion centre midway between the two CeIII ions, which are bridged by two tridentate, two bidentate and four monodentate (within the binuclear unit) acetamide groups. Each Ce atom is nine-coordinated by two N atoms of 1,10-phenanthroline (phen) ligand and four O and three N atoms of anilinoacetamide ligands. The Ce—O and Ce—N bonds are in the range of [2.526 (3)–2.565 (3) Å] and [2.415 (3)–2.828 (4) Å], respectively (Table 1), as in (II) and (III).
In the crystal structure, intermolecular C—H···O, C—H···N, N—H···N and N—H···O hydrogen bonds (Table 2, Fig. 2) result in the formation of a supramolecular network structure; an intramolecular N—H···O hydrogen bond (Table 2) is also present, as in (II) and (III).
The three 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 catena-Poly[hexakis(µ2-anilinoacetamide-O,N)bis- (1,10-phenanthroline-N,N')disamarium(III)], (II), and catena-Poly[hexakis- (µ2-anilinoacetamide-O,N)bis(1,10-phenanthroline-N,N')dipraseodymium(III)], (III), have previously been reported (Liu & Zhu, 2007a,b). 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). We report herein the crystal structure of (I).
In the molecule of (I) (Fig. 1), the ligand bond lengths and angles (Table 1) are within normal ranges (Allen et al., 1987). It has an inversion centre midway between the two CeIII ions, which are bridged by two tridentate, two bidentate and four monodentate (within the binuclear unit) acetamide groups. Each Ce atom is nine-coordinated by two N atoms of 1,10-phenanthroline (phen) ligand and four O and three N atoms of anilinoacetamide ligands. The Ce—O and Ce—N bonds are in the range of [2.526 (3)–2.565 (3) Å] and [2.415 (3)–2.828 (4) Å], respectively (Table 1), as in (II) and (III).
In the crystal structure, intermolecular C—H···O, C—H···N, N—H···N and N—H···O hydrogen bonds (Table 2, Fig. 2) result in the formation of a supramolecular network structure; an intramolecular N—H···O hydrogen bond (Table 2) is also present, as in (II) and (III).
The three compounds, (I), (II) and (III), are isostructural.
