?(2)-Acetone-diacetone[?(3)-tris-(trifluoro-meth-yl)methano-lato]bis-[?(2)-tris-(trifluoro-meth-yl)methano-lato]trilithium.

ABSTRACT: The title compound, [Li(3)(C(4)F(9)O)(3)(C(3)H(6)O)(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 mol-ecule. Two of the Li atoms are further bonded to a non-bridging acetone mol-ecule. Two of the lithium ion coordination geometries are very distorted LiO(4) tetra-hedra; the third could be described as a very distorted LiO(3) 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 tetra-hedrally coordinated species.
