Comment top

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 et al., 1997). The structures of 2-phenoxypropionic acid complexes coupled with their special functionality are our interests. Here, we describe a new Sm^III complex.

The dimeric title compound [Sm₂(C₉H₉O₃)₆(C₁₂H₈N₂)₂] (Scheme I) is centrosymmetric and it comprises of six 2-phenoxypropionate anions and two 1,10-phenanthroline ligands. The Sm^III atoms are bridged by two anions. The Sm^III atom coordinated by two O atoms from two bridging anions, four O atoms from two chelating anions and the N atoms of the N-heterocycle in a dodecahedronal geometry (Fig. 1).

The Sm—Sm separation is 5.1452 (3) Å.

The analysis of structural features indicates that the Sm ion adopts a distorted dodecahedron geometry (Fig. 2) (Ye et al., 2010). Such a geometry is seldom reported and is interesting in lanthanide carboxylate complexes. The L ligands are coordinated to the Sm^III ions in two different modes: chelating and bridging. The Sm—O distances are all within the range 2.199 (3)–2.396 (3) Å, and the Sm—N distances range from 2.459 (3)–2.480 (3) Å, all of which are within the range of those of other eight-coordinated Sm^III complexes with carboxylic donor ligands and 1,10-phenanthroline (Ye et al., 2010). The most significant intermolecular interactions are C—H···O hydrogen bonds(Table 2) and weak π···π aromatic interactions from the phenananthroline molecules and aromatic rings of the anionic ligands.

Experimental top

Reagents and solvents used were of commercially available quality. 2-Phenoxypropionic acid (1.5 mmol), Sm(NO₃)₃^.6H₂O (0.5 mmol) and 1,10-phenanthroline (0.5 mmol) were dissolved in 20 ml e nthanol; 10 ml water was added to the solution. The solution was stirred for 12 h at room temperature. Colorless crystals were obtained after several days.

Special details top

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.
