The title compound, [Li3(C4F9O)3(C3H6O)3], features an open Li/O cube with an Li ion missing at one corner. Three of the four bridging O atoms of the cube carry a fluorinated tert-butyl residue, whereas the fourth is part of an acetone mol­ecule. Two of the Li atoms are further bonded to a non-bridging acetone mol­ecule. Two of the lithium ion coordination geometries are very distorted LiO4 tetra­hedra; the third could be described as a very distorted LiO3 T-shape with two distant F-atom neighbours. The Li⋯Li contact distances for the three-coordinate Li+ ion [2.608 (14) and 2.631 (12) Å] are much shorter that the contact distance [2.940 (13) Å] between the tetra­hedrally coordinated species.

Comment top

Weakly coordinating anions have gained prominence in wide areas of application in research laboratories and industry. One approach is to create such anions by tetrasubstitution of triele derivatives with perfluorinated alkoxides as [OC(CF3)3]- (Reisinger et al., 2007) or with siloxides [OSiR3]- (R = alkyl) (Kern et al., 2008; Lerner et al., 2005, 2002). In this paper we report the crystal structure of the adduct of Li[OC(CF3)3] with acetone, [Li(OC(CH3)2]3[OC(CF3)3]3, (I). According to a literature procedure (Reisinger et al., 2007), Li[OC(CF3)3] was easily accessible from the reaction of HOC(CF3)3 with LiH. Single crystals of (I) were obtained by recrystallization from acetone. Only one comparabel cage structure was found in the Cambridge Crystallographic Database, i.e.3-1,1-diphenylethoxo)-tris(µ2-1,1-diphenylethoxo)-bis(1,1-diphenylethoxy)-tri-magnesium toluene solvate (Zechmann et al., 2001). The title compound features an open Li—O cube with an Li ion missing at one corner. Three of the four bridging O atoms carry a tert.-butyl residue whereas the fourth is part of an acetone molecule. The two four-coordinated Li atoms are further bonded to an acetone molecule. This is the first example of such an Li—O sceleton and only one comparable structure was determined up to now containing Mg instead of Li as metal atoms.

Experimental top

LiH (0.34 g, 43.7 mmol) and Et2O (100 ml) were combined under an N2 atmosphere. Li[OC(CF3)3] (6.1 ml, 43.8 mmol) was added dropwise at ambient temperature. After 1 h at ambient temperature, the solution was heated under reflux for 2 h. Colourless blocks of (I) were obtained by recrystallization from acetone Yield: 6.1 g (50%).

Refinement top

H atoms were located in a difference map, but geometrically positioned and refined using a riding model with fixed individual displacement parameters [U(H) = 1.2 Ueq(C,N)] and with N—H = 0.88Å and C—H = 0.95 Å. The highest peak (2.75 e Å-3) in the final difference electron density map is at 1.36Å from Br1.

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.
