(Received 24 July 2010; accepted 16 September 2010; online 9 October 2010)

In the centrosymmetric dinuclear title complex, [Sm₂(C₁₀H₁₁O₄)₆(C₁₂H₈N₂)₂], the Sm^III ion is nine-coordinated by seven O atoms of five 2-(3,4-dimethoxyphenyl)acetate (DMPA) ligands and two N atoms of one bis-chelating 1,10-phenanthroline (phen) ligand, forming a distorted tricapped trigonal-prismatic environment. The DMPA ligands coordinate in bis-chelate, bridging and bridging tridentate modes. An intramolecular C—H⋯O hydrogen bond occurs. Intermolecular C—H⋯O interactions are also present in the crystal.

Comment top

In recent years, there has been an increasing interest in the coordination chemistry due to the increased recognition of it's importance in magnetism (Yao, et al., 2008; Fang, et al., 2006; Wang, et al., 2008) and antibacterial properties; we have worked in it before (Li, et al., 2008; Liu, et al., 2010). Here we report the crystal structure of a new samarium^III complex with the ligand 3,4-dimethoxylphenyl acetic acid. The title compound consists of two central samarium^III atoms coordinated with six homoveratric acid molecules and two phen molecules. In the bicentric structure, the DMPA ligands coordinate in the bis-chelate, bridging and bridging tridentate modes. Each samarium atom is nine coordinated from seven O atoms from five DMPA molecules and two N atoms from a phen molecule (Fig.1). The samarium^III atom is in a distorted capped square prismatic environment. The Sm—O bond lengths range from 2.397 (2) Å to 2.563 (2) Å and the Sm—N distances range from 2.591 (3) Å to 2.656 (3) Å. Intermolecular interactions (see Table 1) are C—H···O hydrogen bonds and weak π···π aromatic interactions from phen molecules and aromatic rings of the L ligands.

Experimental top

All reagents and solvents used were of commercially available quality and without purified before using. The title compound was obtained by adding Sm₂O₃(0.5 mmol), homoveratric acid (3 mmol) phen (1 mmol) dissolved in 30 ml water, sealed in a 50 ml stainless steel reactor and kept three days at temperature of 433 K. Then the reactor was cooled to room temperature at a speed of 5 K per hour. After filtration of the solution and washing the deposition with ethanol, colorless crystals were obtained.

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.
