The title complex, [Er2(C15H9O2)6(C12H8N2)2], has a centrosymmetric binuclear cage structure in which the two ErIII atoms are both nine-coordinated and are bridged by four bulky anthracene-9-carboxyl­ate (L) ligands, with a non­bonding Er...Er separation of 3.9041 (2) Å. The L groups coordinate each ErIII atom in three different ways. The results reported here reveal that the bulky anthracene skeleton of the L ligand plays an important role in the formation of the complex by virtue of intra- and inter­molecular π–π stacking and C—H...π inter­actions.

Comment top

The rational design and synthesis of functional rare-earth (RE) coordination complexes has attracted great interest because of their fascinating structural diversities and potential uses as functional materials (Bünzli, 2006; Cheng et al., 2006; Fu et al., 2005; Suárez et al., 2004). The most effective and facile approach for the synthesis of such complexes is still the appropriate choice of well designed organic ligands as bridges or terminal groups (building blocks) with metal ions or metal clusters as nodes (Ye et al., 2005). Among various ligands, versatile carboxylic acid ligands exhibiting diverse coordination modes, such as benzoic and naphthalene-1-carboxylic acids (HNCA), have been well used in the preparations of various functional rare-earth complexes (Busskamp et al., 2007; Deacon et al., 2007; Murugesu et al., 2006; Roh et al., 2005; Shi et al., 2001; Wan et al., 2003; Wang et al., 1999, 2006; Yang et al., 2003). In comparison with the aforementioned benzene- and naphthalene-based carboxylic acid ligands, however, far less common has been the use of anthracene-based carboxylic acids, such as the acid used herein, anthracene-9-carboxylic acid (HL).

In our recent research, HNAC and HL have been successfully used to construct a series of novel AgI, CuII, CoII, NiII, MnII, CdII and LaIII complexes having mononuclear, dinuclear, tetranuclear, hexanuclear and one-dimensional chain structures; these complexes also exhibited interesting magnetic and luminescent properties (Liu, Chang & Wang, 2007; Liu, Chen et al., 2008; Liu et al., 2006; Liu, Wang et al., 2007; Liu, Yan et al., 2008; Zou et al., 2005). To further explore the coordination architectures of the HL ligand bearing the bulky anthracene skeleton in this research, a new ErIII complex with L has been synthesized by taking advantage of the carboxylate bridging coordination abilities of the ligand and the steric bulk of its anthracene ring system, while also incorporating 1,10-phenanthroline (phen) as a chelating co-ligand. We report here the synthesis and the crystal structure of the title complex, (I).

The structure of (I) consists of a centrosymmetric dinuclear [Er2(L)6(phen)2] unit, in which each ErIII ion is nine-coordinated by two N-atom donors from one chelating phen ligand and seven O atoms from five distinct L ligands (Fig. 1). The Er—O distances are in the range 2.2721 (16)–2.6123 (16) Å, which are in the normal range and in agreement with those found in other carboxylate-containing ErIII complexes (Cheng et al., 2006). The phen ligand acts as a typical chelating ligand, coordinating to the ErIII ion with Er—N bond distances of 2.558 (2) and 2.6132 (19) Å and an N1—Er1—N2 angle of 63.63 (7)°. For L, there exist three different forms of carboxylic coordination mode with the ErIII center, namely bidentate syn–syn bridging (µ2-η1:η1-bridging), symmetric bidentate chelating (µ1-η1:η1-chelating) and tridentate chelating/bridging (η-O,O'-µ-O,O) coordination modes, which jointly connect the two ErIII atoms to form an eight-membered ring composed of atoms Er1, O5, C1, O6A, Er1A, O5A, C1A and O6, as well as a four-membered ring composed of atoms Er1, O3, Er1A and O3A, with a nonbonding Er1···Er1A separation of 3.9041 (2) Å [the suffix A denotes the symmetry operation (-x + 1, -y + 1, -z + 1)]. Intramolecular face-to-face ππ stacking is observed between the anthracene and phenanthroline ring systems in the dinuclear unit, with a centroid–centroid separation of 3.636 (5) Å, an average interplanar separation of 3.486 Å, and a dihedral angle of 4.8° (Janiak, 2000). In addition, adjacent dinuclear [Er2(L)6(phen)2] units are arranged into a one-dimensional chain along the [111] direction by intermolecular ππ stacking interactions (symmetry operation: -x + 2, -y + 2, -z + 2; see Fig. 2) between the completely parallel anthracene rings of distinct L ligands, with a centroid–centroid separation of 3.743 (2) Å.

Moreover, complex (I) contains intra- and intermolecular C—H···π interactions (Table 2) involving the C25–C30 (centroid Cg1) and C10–C15 (centroid Cg2) benzene rings of the L ligands and the C52–C56/N2 (centroid Cg3) pyridine rings of the phen ligands, with an edge-to-face orientation that interlinks the dinuclear subunits into two different one-dimensional chains along the [100] and [110] directions, respectively (Fig. 3). The result is a two-dimensional network running parallel to the (001) plane (Sony & Ponnuswamy, 2006). As we have found previously (Liu, Chang & Wang, 2007 and/or Liu, Wang et al., 2007)??, such bulky anthracene-based carboxylate ligands have a large conjugated π system and thus ππ stacking and/or C–H···π interactions play an important role in the formation of the supramolecular framework. Isolation of complex (I), therefore, is a new proof of the coordination versatility of simple monocarboxylic acid ligands bearing a bulky anthracene ring skeleton.

Experimental top

A mixed solution of HL (0.05 mmol) and phen (0.05 mmol) in CH3OH (10 ml) in the presence of excess 2,6-dimethylpyridine (ca 0.05 ml for adjusting the pH value to basic conditions) was carefully layered on top of an aqueous solution (15 ml) of Er(NO3)3 (0.1 mmol) in a test tube. Yellow single crystals of (I) suitable for X-ray analysis appeared on the tube wall after ca two weeks at room temperature (yield ~30% based on HL). Elemental analysis calculated for C114H70Er2N4O12: C 67.71, H 3.49, N 2.77%; found: C 67.85, H 3.57, N 2.69%.

Refinement 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.
