The structure of the title compound, (C3N2H5)3[Dy(C7H3NO4)3]·3H2O, contains a mononuclear DyIII complex with the rare earth metal cation in a distorted tricapped trigonal–prismatic environment. The DyIII ion is in each case O,N,O′-chelated by three tridentate pyridine-2,6-dicarboxyl­ate anions. Three protonated imidazole mol­ecules act as counter-cations and three lattice water mol­ecules are also present. Numerous N—H⋯O and O—H⋯O hydrogen bonding inter­actions, some of which are bifurcated, help to stabilize the packing of the structure.

In recent years, the interaction of pyridine-2,6-dicarboxylic acid (H2pdc) with several metal ions has been extensively studied due to its unique ability to form stable chelates in diverse coordination modes such as bidentate, meridian and bridging (Kjell et al., 1993). A considerable number of metal—pdc complexes have been synthesized and their structures determined over the past decade (Huang et al., 2008; Ghosh et al., 2005; Song et al., 2005; Wu et al., 2008; Yue et al., 2005; Zhao et al., 2005, 2007). Here we present the structure of the title compound (C3N2H5)3[Dy(C7H3NO4)3].(H2O)3, which includes pyridinedicarboxylate (pdc2-) anions and imidazolium (im) counter cations.

The crystal structure is composed of a mononuclear DyIII complex with the rare earth metal cation in a distorted tricapped trigonal-prismatic environment (Fig. 1, Table 1). The DyIII ion is in each case O,N,O-chelated by three tridentate pyridine-2,6-dicarboxylate (pda2-) ligands. Three imidazolium molecules act as counter cations. Moreover, three lattice water molecules are present. Numerous N—H···O, O—H···O and O—H···N hydrogen bonding interactions (Table 2), part of which are bifurcated, lead to a three-dimensional assembly of the structural building blocks.

Experimental top

The title compound was synthesized under solvothermal conditions. A mixture of pyridine-2,6-dicarboxylic acid (0.0334 g, 0.2 mmol), Dy(NO3)3.6H2O (0.0245 g, 0.06 mmol), imidazole (0.0340 g, 0.5 mmol) and H2O / C2H5OH (v / v = 1: 1, 2.5 ml) was sealed in a 6 ml glass tube and heated to 393 K for 72 h. After cooling to room temperature, colorless block-like crystals were obtained.

Refinement top

H atoms bound to C and N atoms were placed in calculated positions with C—H = 0.93 and N—H = 0.86 Å and refined in riding mode, with Uiso(H) = 1.2 Ueq(N, C). H atoms attached to water molecules were located in Fourier maps and refined with distance constraints of 0.85 Å and Uiso(H) = 1.5 Ueq(O).

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.
