Solvent-free thallium(I) tetrakis[3,5-bis(trifluoromethyl)phenyl]borate: crystal structure, supramolecular interactions and anisotropic thermal expansion
The solvent-free structure of the thallium(I) salt of the weakly coordinating anion tetrakis[3,5-bis(trifluoromethyl)phenyl]borate, Tl[BC32H12F24], exhibits short Tl⋯F contacts and a supramolecular architecture governed by C—H⋯F hydrogen bonds and weak F⋯F and C—F⋯π interactions. Disorder and tilting of the arene rings...
