An Eu-based metal–organic framework: poly[[tris­(μ₄-benzene-1,4-dicarboxyl­ato)bis­(μ₂-N,N-diethyl­formamide)dieuropium(III)] 0.7-hydrate]

The crystal structure of the title compound, {[Eu₂(C₈H₄O₄)₃(C₅H₁₁NO)₂]·0.7H₂O}_n, consists of chains formed by Eu atoms ­connected by the carboxyl­ate groups of the benzene-1,4-dicarboxyl­ate (BDC) linker. The chains are inter­connected by BDC linkers, generating a three-dimensional framework with large voids. The Eu atoms are coordinated by seven carboxyl­ate O atoms and one solvent O atom in a sterically constrained manner due to the carboxyl­ate group rigidity, and this causes the coordination to be distorted dodeca­hedral. The ethyl groups of the solvent ligand are disordered in the void. The elongated Eu—O bond to the solvent indicates that it is loosely bound to the framework, and hence solvent exchange may be possible. In the void there is additionally one partly occupied disordered water mol­ecule.

Special details

Experimental. A correction for the oblique incidence of the X-ray beam through the detector has been made using a transmission factor of 0.37 for the MarCCD detector measured at a wavelength of 0.55 Å.

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.
