Abstract top

The title compound, {[Dy2(C4H4O4)3(H2O)2]·H2O}n, is isostructural with other lanthanide succinates of the same formula. The DyIII atom is nine-coordinated in a tricapped trigonal-prismatic environment by eight O atoms, derived from six carboxylate groups and a water molecule. One of the independent succinate anions is located about a crystallographic inversion center and the uncoordinated water molecule lies on a twofold axis. The crystal structure comprises edge-shared DyO9 polyhedra linked by succinate bridges, forming a three-dimensional network architecture. Intra- and intermolecular O-H...O hydrogen bonds are present in the crystal structure.

Comment top

There is considerable interest in the study of coordination frameworks with suitable rigid multidentate ligands. Especially those having long chain dicarboxylates present interesting behavior owing to their conformational flexibility and coordination diversity. Lanthanide ions exhibit high affinity for oxygen and diverse coordination modes. In an attempt to further understand the formation of lanthanide–organic framework materials, we present here the hydrothermal synthesis and crystal structure of a new Ln–succinate complex, (I).

The title compound, (I), is isostructural with the known Ln–succinate complexes where Ln = Y and La (Perles et al., 2004), Pr (Serpaggi & Ferey, 1999), Nd (He et al., 2007), Sm (Seguatni et al., 2004), Gd (Zhou et al., 2005), Tb (Cui et al., 2005), Ho (Yu et al., 2006), and Er (Li, 2007) analogs, but it represents the first reported succinate coordination polymer of dysprosium (III).

The asymmetric unit in (I) comprises a Dy atom, one and a half succinate anions, a coordinated water molecule and half an uncoordinated water molecule (Fig. 1). The complete second succinate dianion, containing O5 and O6, is generated from the half-ion by inversion and the uncoordinated water molecule O atom is located on a twofold axis. The DyIII ion is nine-coordinated within a tricapped trigonal-prismatic geometry defined by eight O atoms, derived from six carboxylate anions, and a water molecule. The crystal structure comprises edge–sharing DyO8(OH2) polyhedra forming chains along the b–axis direction by sharing one edge with each neigboring polyhedron. The Dy···Dy distance within chains is 4.046 (1) Å. These chains are in turn linked via succinate bridges, forming a three-dimensional framework (Fig. 2.). Intra- and intermolecular O–H···O hydrogen bonds are present in the crystal structure (Table 1).

Experimental top

A mixture of Dy(NO3)3.7H2O (0.1316 g, 0.30 mmol), succinic acid (0.0354 g, 0.30 mmol), 1,10-phenanthroline (0.0595 g, 0.30 mmol), water (10 ml) was adjusted to a pH = 5.25 by NaOH solution. The mixture was sealed in a Teflon-lined stainless steel reactor and heated at 443 K for 3 d. After the reaction system had cooled slowly to room temperature, a small quantity of colourless crystals was isolated.

Refinement top

H atoms bonded to C atoms were placed in their geometrically calculated positions and refined using the riding model, with C–H distances 0.97 Å and Uiso(H) = 1.2 Ueq(C). H atoms attached to O atoms were found in a difference Fourier map and then refined using the riding model, with O–H distances fixed as initially found and with O–H distances 0.85 Å and Uiso(H) values set at 1.2 Ueq(O).

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.
