In the title compound, [Eu2(C6H5NO3)2(C2O4)3(H2O)4]n, the EuIII atom is bonded to one O atom from a monodentate 5-hy­droxy­pyridin-1-ium-3-carboxyl­ate ligand, six O atoms from three oxalate ligands and two water mol­ecules, exhibiting a highly distorted tricapped trigonal geometry. Three independent oxalate ligands, each lying on an inversion center, bridge the EuIII atoms, forming a brickwall-like layer parallel to (001), which is stabilized by intra­layer O—H⋯O hydrogen bonds. The layers are further linked through inter­layer O—H⋯O and N—H⋯O hydrogen bonds and ππ inter­actions between the pyridine rings [centroid–centroid distance = 3.5741 (14) Å] into a three-dimensional supra­molecular network.

Comment top

Pyridine-carboxylic derivatives are of resent interest in coordination polymers due to their structural diverity and unique physical properties (Black et al., 2009; Cañadillas-Delgado et al., 2010). Some transition and/or rare earth metal complexes with pyridine-2,5/6-dicarboxylic acid (Sun et al., 2010; Wen et al., 2007) or 2/6-hydroxynicotinic acid (Hu et al., 2007; Xu et al., 2008) have been prepared and documented. Recently, a few coordination polymers from 5-hydroxynicotinic acid are reported, in which the multidentate bridging ligand exhibits versatile coordination modes in constructing transition metal (Yang et al., 2011) and rare earth metal (Zhang et al., 2012) organic frameworks. The research interest in europium(III) coordination polymers with the ligands comes from their luminescent properties (Decadt et al., 2012; Gai et al., 2012; Ramya et al., 2012) and applications (Bunzli, 2010). Here, we report the crystal structure of an europium(III) complex of a pyridine-carboxylic derivative.

The title compound is isostructural with its Tb(III) and Sm(III) analogues (Zhang et al., 2012). As shown in Fig. 1, the asymmetric unit contains an EuIII ion, a 3-H-5-hydroxynicotinate ligand, one and half oxalate ligands and two coordinated water molecules. The EuIII ion is bonded to nine O atoms, one from the 3-H-5-hydroxynicotinate ligand, six from three oxalate ligands and two from the water molecules, exhibiting a highly distorted tricapped trigonal geometry. The EuIII ions are linked by the oxalate ligands into a brickwall-like layer parallel to (001) (Fig. 2), with Eu···Eu distances of 6.1886 (3), 6.2845 (3) and 6.4206 (3) Å. In the compound, the three oxalate ligands are centrosymmetric and bridge metal ions in a side-by-side coordination manner. The layers are stabilized by intralayer O—H···O hydrogen bonds and further linked through interlayer O—H···O hydrogen bonds and ππ interactions between the pyridine rings [centroid–centroid distance = 3.5741 (14) Å] into a three-dimensional supramolecular network.

Experimental top

A mixture of europium nitrate (0.4 mmol, 0.186 g), 5-hydroxynicotinic acid (0.8 mmol, 0.112 g), ammonium oxalate (0.8 mmol, 0.099 g) and 10 ml water was sealed in a 15 ml Teflon-lined autoclave. Colorless crystals suitable for X-ray analysis were obtained by heating the mixture at 443 K for 70 h and then cooled down to room temperature at a rate of 5 K/h (yield: 45%). Analysis, calculated for C9H9EuNO11: C 23.54, H 1.98, N 3.05%; found: C 23.36, H 2.02, N 3.01%.

Refinement top

C-bound H atoms and H atom on hydroxyl were positioned geometrically and refined as riding atoms, with C—H = 0.93 and O—H = 0.82 Å and with Uiso(H) = 1.2(1.5 for hydroxyl)Ueq(C,O). Other H atoms were located from a difference Fourier map and refined isotropically.

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.
