Abstract top

In the title compound, [Gd(C8H6NO2)3(H2O)]n, the gadolinium(III) ion is coordinated by eight carboxylate O atoms and one water molecule. The carboxylate ligands bridge pairs of gadolinium(III) ions, forming a zigzag chain along [100]. Hydrogen bonds link the chains into sheets parallel to (001).

Comment top

The bifunctional ligand 3-pyridylacrylic acid (HTPA) is a potential multidentate ligand,and several types of complexes of HTPA have been studied (Ayyappan et al. ,2001; Gunning & Cahill, 2005; Zhang et al., 2000). Until now, however, only a few crystallographic studies of 4f-block metal complexes of HTPA have been reported (Liu et al., 2006; Liu et al., 2004; Zhou et al., 2004).

Here, we reported the synthesis and structure of the title complex, [Gd(TPA)3(H2O)]n (Fig.1), whose structure consists of a repeating unit of formula [Gd(TPA)3(H2O)]. Each GdIII centre is coordinated by eight carboxylate O atoms and one water molecule. The gadolinium(III) ions are joined into a coordination polymer chain along [100] (Fig.2), reinforced by O—H···O hydrogen bonds. Adjacent [100] chains are linked by O—H···N hydrogen bonds, forming sheets parallel to (001) (Fig.3).

Experimental top

A mixture of Gd(NO3)3.6H2O (0.25 mmol, 0.110 g), 3-pyridylacrylic acid (1.25 mmol,0.186 g), H2O (14 ml) was sealed in a 25 ml Teflon-lined stainless reactor and heated at 438 K for four days under autogenous pressure, then followed by slow cooling to room temperature, when a few colourless crystals were obtained. Analysis:found C 46.55, H 3.28, N 6.85%; C24H20GdN3O7 requires C 46.48, H 3.23, N 6.78%.

Refinement top

H atoms of the water molecules were located in a difference map and freely refined. H atoms bonded to C atoms were placed at calculated positions and treated using a riding-model approximation [C—H = 0.93Å and Uiso(H)= 1.2Ueq(C)].

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.
