μ(2)-Acetone-diacetone[μ(3)-tris(trifluoromethyl)methanolato]bis[μ(2)-tris(trifluoromethyl)methanolato]trilithium
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 molecule. Two of the Li atoms are further bonded...

Sumario: | 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 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 LiO(4) tetrahedra; 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 tetrahedrally coordinated species. |
