In the colourless title compound, [Pr(CF3O3S)3(CH3CN)3]n, the three trifluoro­methane­sulfonate anions form three bridges via O:O′-coordination between two PrIII atoms. The structure contains [Pr(NCMe)3-μ2(OTf)3—Pr(NCMe)3-μ2(OTf)3]n (NCMe is acetonitrile; OTf is trifluoromethanesulfonate) chains parallel to the a axis. The PrIII atom is nine-coordinate in a distorted tricapped trigonal-prismatic environment.

Supporting information


Comment top

The coordination environment of the PrIII atom ion in the title compound can be described as a distorted trigonal tri-capped prism. 6 O atoms are forming the trigonal prismatic environment around the PrIII atom and the three N atoms of the coordinated MeCN solvent molecules are forming the cappings over the rectangular sides of the prism. The metal-O distances in the title compound are with an average of 2.458 (13) Å about 0.05 Å longer than in the corresponding Eu complex (Tang et al., 2011) and 0.04 Å shorter than in its U analogue (Natrajan et al., 2005) reflecting the effects of the lanthanide contraction and also the change from a lanthanide to an actinide ion. The metal-N distances with 2.588 (17) Å for the Eu complex are about 0.05 Å shorter than for the here presented Pr compound with 2.640 (17) Å, whereas the latter are found to be in very good agreement with those in the U complex with 2.651 (14) Å. The ion size increase while changing the metal ion in the complex from Pr to U seems to influence more the shorter metal-O distances than the longer metal-N distances for the solvent molecules forming the cappings of the trigonal prism.

Experimental top

Crystals from the title compound precipitated after a ligand exchange reaction from 103.1 mg (0.13 mmol) [Pr(H2O)9](OTf)3 in 2 ml of MeCN. Crystals in the form of needles suitable for x-ray analysis were obtained by re-crystallization from hot MeCN.

Refinement top

All H atoms were placed on geometrical positions according to the hybridization of the atoms they are bound to. One common isotropic U value was used and refined for all hydrogen atoms.

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.
