Lithium–tetra­kis­(penta­fluoro­phen­yl)borate–­benzene (1/1/2)

The title compound, Li⁺·C₂₄BF₂₀⁻·2C₆H₆, crystallizes as centrosymmetric dimers, with two η⁶-coordinated and two uncoordinated mol­ecules of benzene per dimer. There are two crystallographically independent dimers.

(2-Chloro­anilino)acetophenone

The title compound, C₁₄H₁₂ClNO, is used in perfumery, as a catalyst for the polymerization of olefins, and in organic synthesis, especially as a photosensitizer and in the manufacture of dyes. The mol­ecule is essentially planar and has a trans configuration. In this configuration, the Cl and O atoms shield the amino H atom, preventing the formation of an inter­molecular hydrogen bond.
