In the centrosymmetric binuclear title complex, [Ce2(C9H9O3)6(C12H8N2)2], the two CeIII ions are linked by four 2-phenoxypropionate groups in bi- and tridentate bridging modes. Each CeIII ion is nine-coordinated by one 1,10-phenanthroline molecule, two O atoms from a chelating carboxylate, two O atoms derived from a μ3-carboxylate and two O atoms derived from two μ2-carboxylate ligands in a distorted CeN2O7 monocapped square-antiprismatic geometry.

Reagents and solvents used were of commercially available quality and without purified before use. 2-Phenoxypropionic acid (1.5 mmol), Ce(NO3)3.6H2O (0.5 mmol) and 1,10-phenanthroline (0.5 mmol) were dissolved in 20 ml enthanol, then 10 ml water were added to the above solution. The mixed solution was stirred for 12 h at room temperature. Finally, the deposit was filtered off and the colourless solution was kept in the open air. Colourless crystals were obtained after several days.
The structure was solved by
and successive Fourier difference synthesis. The H atoms bonded to C and N atoms were positioned geometrically and refined using a riding model [aliphatic C—H =0.96 Å (Uiso(H) = 1.5Ueq(C)), aromatic C—H = 0.93 Å (Uiso(H) = 1.2Ueq(C))].The group of phenoxyalkanoic acids includes a considerable number of important herbicides. The desired biological activity is largely dependent on the length of the carbon chain of the alkanoic acid, the nature of the phenoxy group, and the position of its attachment to the carbon chain (Markus & Buser, 1997). The structures of 2-phenoxypropionic acid (HL) complexes coupled with their special functionality catched our interest. Here, we describe the CeIII title complex, (I).
The structure of complex (I) is shown in Fig. 1 and the coordination environment of Ce(III) is shown in Fig. 2. The dimeric title compound (I) is centrosymmetric and is comprised of six L anions and two phenanthroline ligands. The two Ce(III) ions are linked together by four L groups through their bi- and tri-dentate bridging modes, forming a dimeric unit. The distance between two La(III) ions in the dimeric unit is 4.1025 (3) Å. Each Ce(III) ion is coordinated by nine atoms, five of which are oxygen atoms from the bridging carboxylates, two oxygen atoms from the bidentate chelating carboxylate group, and two nitrogen atoms from a 1,10-phenanthroline molecule. The Ce(III) ion adopts a distorted monocapped square antiprisatic geometry (Fig. 2). The Ce—O distances are within the range 2.4377 (19)–2.694 (2) Å, and the Ce—N distances rang from 2.643 (2)–2.691 (2) Å, all of which are within the range of those of other nine-coordinated CeIII complexes with carboxylic donor ligands and 1,10-phenanthroline (Fu et al., 2007) (Table 1).

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 group of phenoxyalkanoic acids includes a considerable number of important herbicides. The desired biological activity is largely dependent on the length of the carbon chain of the alkanoic acid, the nature of the phenoxy group, and the position of its attachment to the carbon chain (Markus & Buser, 1997). The structures of 2-phenoxypropionic acid (HL) complexes coupled with their special functionality catched our interest. Here, we describe the CeIII title complex, (I).
The structure of complex (I) is shown in Fig. 1 and the coordination environment of Ce(III) is shown in Fig. 2. The dimeric title compound (I) is centrosymmetric and is comprised of six L anions and two phenanthroline ligands. The two Ce(III) ions are linked together by four L groups through their bi- and tri-dentate bridging modes, forming a dimeric unit. The distance between two La(III) ions in the dimeric unit is 4.1025 (3) Å. Each Ce(III) ion is coordinated by nine atoms, five of which are oxygen atoms from the bridging carboxylates, two oxygen atoms from the bidentate chelating carboxylate group, and two nitrogen atoms from a 1,10-phenanthroline molecule. The Ce(III) ion adopts a distorted monocapped square antiprisatic geometry (Fig. 2). The Ce—O distances are within the range 2.4377 (19)–2.694 (2) Å, and the Ce—N distances rang from 2.643 (2)–2.691 (2) Å, all of which are within the range of those of other nine-coordinated CeIII complexes with carboxylic donor ligands and 1,10-phenanthroline (Fu et al., 2007) (Table 1).
