Abstract top

In the title coordination polymer, [Zr(C8H2O6)(C6H12N2O)2]n, the ZrIV atom, which lies on a crystallographic twofold rotation axis, is coordinated by two O,O'-bidentate 2,5-dioxidoterephthalate (DHTP4-) ligands and two O-bonded 1,3-dimethyl-1,3-diazinan-2-one (DMPU) ligands (the latter in a cis orientation) in a distorted ZrO6 octahedral geometry. The deprotonated hydroxy and carboxy O atoms of the DHTP4- ligand chelate the ZrIV ion via a six-membered ring; the dihedral angle between the carboxylate group and the aromatic ring is 19.94 (11)°. The DHTP4- ligand is completed by crystallographic inversion symmetry and coordinates to two ZrIV atoms, thereby forming polymeric zigzag chains propagating in the c-axis direction.

Comment top

The title compound was synthesized as a part of a larger project (see also Maercz et al., 2013), in which the possibility to form new zirconium containing metal organic frameworks (MOFs) using the linker 2,5-dihydroxyterephthalic acid (DHTP) was investigated. Zirconium containing MOFs (Chavan et al., 2012) using terephthalic acid have shown extraordinary thermal stability whereas DHTP containing MOFs (Dietzel et al., 2005, 2006) have shown remarkable sorption properties.

Experimental top

Zirconium(IV) chloride (0.047 g, 0.2 mmol) and 2,5-dihydroxyterephthalic acid (0.040 g, 0.2 mmol) were dissolved in 5 ml N,N'-dimethylpropylene urea (DMPU) in a Teflon liner of 23 ml volume under inert atmosphere in a glovebox. The teflon liner was sealed and put into a steel autoclave. The mixture was reacted for 3 d at 160°C. Reaction yielded a brown substance consisting of block shaped crystals and a white impurity. The product was collected by filtration, washed with DMPU and dried over night at room temperature in ambient atmosphere.

Refinement top

Hydrogen atoms were placed geometrically in ideal positions and refined using a riding model, the Uiso set to 1.5 times the thermal parameter of the carbon atom to which they are attached for methyl groups and 1.2 times for other hydrogen atoms.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
