In the title compound, {[NaTb(C7H6NO2)4(H2O)2]·C2H5OH·H2O}n, the TbIII atom is eight-coordinated in a slightly distorted square-antiprismatic geometry defined by four carboxylate O atoms and four pyridine N atoms. The bond lengths lie within the range 2.3000 (2)–2.326 (2) Å for the Tb—O bonds and 2.543 (3)–2.553 (3) Å for the Tb—N bonds. The NaI atom is five-coordinated by two water O atoms and three carboxylate O atoms in a distorted square-pyramidal geometry. In the crystal, intermolecular O—H⋯O hydrogen bonds link the molecules into a three-dimensional network.

Terbium trichloride solution was prepared by dissolving TbCl3.6H2O (0.27 g, 1.0 mmol; Aldrich) in absolute ethanol (20 ml) at room temperature with stirring. The ligand solution was prepared by dissolving 3-methylpicolinic acid (0.55 g, 4.0 mmol; Aldrich) in absolute ethanol (30 ml) at room temperature with stirring. The pH of the ligand solution was adjusted to about 5.1 with 2 N NaOH solution. The Terbium trichloride solution was added dropwise slowly to the ligand solution. The reaction mixture was stirred for 1 h at room temperature. Colourless crystals of (I) were obtained at room temperature over a period of a few weeks. The complex was recrystallized from the mixture of distilled water and absolute ethanol solution.
The O—H atoms were located in a difference Fourier map and refined with O—H = 0.81±0.01 Å. The remaining H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.97 Å, and with Uiso(H) = 1.2Ueq (C) for aromatic and methylene-H and 1.5Ueq(C) for methyl-H atoms. The maximum and minimum residual electron density peaks of 0.51 and -0.56 e Å-3, respectively, were located 0.85 Å and 0.57 Å from the Tb1 atom, respectively.
Luminescent metal compounds with N-containing ligands have been reported in the investigation of their interesting photophysical properties and various coordination modes (Seo et al., 2010; Zhou et al., 2010; Fan et al., 2009). Especially, lanthanide metal complexes have been extensively studied due to their unique luminescence properties (Lis et al., 2009; Godlewska et al., 2008; Legendziewicz, 2002). As an extension of our work (Kang, 2010; Oh et al., 2010; Kim et al., 2010; Seo et al., 2009) on luminescent complexes, herein, we report the
and luminescent properties of the title Tb(III) chloride complex with 3-methylpyridine-2-carboxylic acid (3-methylpicolinic acid), (I).In the title compound, {[NaTb(H2O)2(C7H6NO2)4].C2H5OH.H2O}n, the TbIII atom is eight-coordinated within a slightly distorted square antiprismatic geometry. The TbIII atom is coordinated to the four carboxylate-O atoms and four pyridine-N atoms. The Tb—O bond distances are within the range of 2.300 (2)–2.326 (2) Å (Table 1), which are significantly shorter than the sum of the covalent radii of Tb and O atoms (2.420 Å). The Na+ ion is five-coordinated with two water-O atoms and three carboxylate-O atoms to form a distorted square pyramidal geometry. In the
intermolecular O—H···O hydrogen bonds (Table 2) link the uncoordinated water molecule to the coordinated picolinic ligands and further link the molecules into a three-dimensional network.The title compound exhibits an intense emission at 543 nm upon 326 nm excitation in PL spectra with 325 nm of He—Cd laser excitation wavelength

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. |

Luminescent metal compounds with N-containing ligands have been reported in the investigation of their interesting photophysical properties and various coordination modes (Seo et al., 2010; Zhou et al., 2010; Fan et al., 2009). Especially, lanthanide metal complexes have been extensively studied due to their unique luminescence properties (Lis et al., 2009; Godlewska et al., 2008; Legendziewicz, 2002). As an extension of our work (Kang, 2010; Oh et al., 2010; Kim et al., 2010; Seo et al., 2009) on luminescent complexes, herein, we report the crystal structure and luminescent properties of the title Tb(III) chloride complex with 3-methylpyridine-2-carboxylic acid (3-methylpicolinic acid), (I).
In the title compound, {[NaTb(H2O)2(C7H6NO2)4].C2H5OH.H2O}n, the TbIII atom is eight-coordinated within a slightly distorted square antiprismatic geometry. The TbIII atom is coordinated to the four carboxylate-O atoms and four pyridine-N atoms. The Tb—O bond distances are within the range of 2.300 (2)–2.326 (2) Å (Table 1), which are significantly shorter than the sum of the covalent radii of Tb and O atoms (2.420 Å). The Na+ ion is five-coordinated with two water-O atoms and three carboxylate-O atoms to form a distorted square pyramidal geometry. In the crystal structure, intermolecular O—H···O hydrogen bonds (Table 2) link the uncoordinated water molecule to the coordinated picolinic ligands and further link the molecules into a three-dimensional network.
The title compound exhibits an intense emission at 543 nm upon 326 nm excitation in PL spectra with 325 nm of He—Cd laser excitation wavelength
