The title compound, [Pr2(C8H10O4)3(H2O)4]n is a three-dimensional metal–organic framework built of chains of edge-sharing PrIII polyhedra by the e,e-trans-cyclo­hexane-1,4-dicarboxyl­ate (chdc) dianions. There are two types of Pr atoms (one in a ten-coordinate and the other in a nine-coordinate geometry) and four types of chdc ligands. One Pr atom is coordinated by eight carboxylate O atoms from five chdc and two water mol­ecules, whereas the other is coordinated by seven carboxylate O atoms from five chdc and two water mol­ecules. Two of the four chdc ligands are located on inversion centers. The ligation of alternate Pr atoms by the carboxylate groups of chdc ligands leads to an infinite chain; the chains are further connected with six neighboring chains through the chdc ligands, resulting in a three-dimensional network.

Comment top

Cyclohexane-1,4-dicarboxylic acid (chdcH2) is a flexible ligand for constructing functional metal-organic frameworks (Kurmoo et al., 2003, Kurmoo et al., 2006, Qi et al., 2003, Rao et al., 2007). In our previous work, we have also isolated a photoluminescent zinc cyclohexane-1,4-dicarboxylate (Yu et al., 2007). When investigating the reaction of chdcH2 and Pr3+ ions, a compound formulated as [Pr2(C8H10O4)3(H2O)4]n (I) was obtained.

The compound is a three-dimensional framework built from infinite chains of edge-sharing Pr polyhedra that are interconnected by the –C6H12– cyclohexane rings of chdc ligands. There are two Pr atoms, three chdc and four coordinated water molecules in the asymmetric unit (Figure 1). There are four types of chdc ligands and two types of Pr atoms. The four chdc dianions are in an e,e-trans conformation. Their coordination modes, shown in Figure 2, are denoted as α, β, γ and δ. The Pr1 is coordinated by eight carboxyl O atoms from five chdc (two α, two β, one γ) and two water molecules in a distorted dicapped square-antiprismatic enviroment whereas the Pr2 is coordinated by seven carboxyl O atoms from five chdc (two α, two β, one δ) and two water molecules in a distorted tricapped trigonal-prismatic enviroment. The Pr—O bond lengths range from 2.451 (3) to 2.828 (3) Å. There are hydrogen bonding interactions involving the water molecules and some carboxyl O atoms. The ligation of alternating Pr1 and Pr2 atoms by the carboxyl groups of chdc ligands leads to an infinite chain (Figure 3). Each chain connects with six neighboring chains through chdc ligands to result in a three-dimensional framework (Figure 4).

Experimental top

A mixture of PrCl3.6H2O (0.5 mmol, 0.178 g), chdcH2 (0.8 mmol, 0.137 g), and water (10 ml) adjusted by dilute NaOH solution to around pH 4 was sealed in Teflon-lined autoclave and heated at 180 °C for 4 days, followed by slow cooling to room temperature. Compound (I) was collected as green block crystals with yield about 75% based on Pr.

Refinement top

H atoms on water molecules were located in a difference Fourier map, and fixed with O—H = 0.85 Å and Uiso(H) = 1.2 Ueq(O). The others on C atoms are placed in calculated positions and refined in the riding model approximation with C—H = 0.97 or 0.98 Å and Uiso(H) = 1.2 Ueq(C). The highest peak and deepest hole in the final electron-density difference map were 0.506 Å and -0.897 Å, respectively.

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.
