Abstract top

In the title complex, [Gd(C11H10N3O2)3]·0.5CH4O·2.5H2O, the Gd atom is coordinated by six N atoms and three O atoms derived from three tridentate monoanionic 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The molecules are linked together via hydrogen bonds involving the solvent water and methanol molecules.

Comment top

Recently we reported the crystal structures of bis(6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato)zinc(II) trihydrate (Yin et al., 2007) and bis[3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato]cobalt(II) 2.5- hydrate (Zhao et al., 2007). As a continuation of these investigations, we report in this paper the crystal structure of tris(6-(3,5-dimethyl-1H-pyrazol-1-yl))picolinato)gadolinium(III) 2.5 hydrate 0.5 methanol solvate.

In the title complex, the gadolinium(III) ion is nine-coordinated by six N atoms and three O atoms derived from the tridentate ligands, 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate (DPP); the angles around Gd(III) atom range from 60.34 (15) to 149.67 (16) °, the Gd—O bond lengths are 2.320 (4), 2.343 (4) and 2.372 (4) Å, The Gd—N distances range from 2.512 (5) to 2.742 (5) Å, i.e. normal values. The C1—C2 bond length is 1.520 (9) Å, being in the normal C—C ranges for gadolinium carboxylate complexes.

In the crystal structure, the oxygen atoms contribute to the formation of intermolecular hydrogen bonds involving the solvate molecules that link the complex into a three-dimensional network. (Fig. 2; for symmetry codes see Table 2).

Experimental top

6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinic acid, and GdCl3. 6H2O were available commercially and were used without further purification. Equimolar 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinic acid (1 mmol, 217 mg) was dissolved in anhydrous ethyl methanol (AR, 99.9%) (15 ml). The mixture was stirred to give a clear solution, To this solution was added GdCl3.6H2O (0.33 mmol, 99 mg) in anhydrous methanol (10 ml). After keeping the resulting solution in air to evaporate about half of the solvents, colorless blocks of the title complex were formed. The crystals were isolated, washed with alcohol three times (yield, 75%). Elemental analysis: found: C, 46.31; H, 4.37; N, 14.46; calc. for C67H74Gd2N18O18: C, 46.41; H, 4.30; N, 14.54.

Refinement top

H atoms on C atoms were positoned geometrically and refined using a riding model with C—H = 0.96Å and Uiso(H) = 1.2Ueq(C). The water H atoms were located in difference Fourier maps and the O—H distances were constrained to 0.85 Å, with Uiso(H) = 1.2Ueq(O). The methanol O—H hydrogen atom was constrained with O—H distance of 0.82 Å. There are five waters of hydration sites and one methanol solvate site; all of these atoms were refined at half- occupancy. The largest difference map peaks are in the region of the disordered solvate molecules and probably represent alternative water and methanol sites that were not modeled.

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.
