Structural diversity in nonafluoromesityl chemistry
Abstract
Several new compounds containing the nonafluoromesityl substituent [2,4,6-tris(trifluoromethyl)phenyl, abbreviated as RF] have been prepared and structurally characterized. Solid state structures are reported for C5Me5P(Cl)RF (1), Sn(SeRF)4 (3), Te(RF)2 (4) and (AgRF)4 (5). 1 and 4 crystallize in space group P21/c, 3 in space group P, and 5 in space group I41/a. While 1 and 3 are monomeric in the solid state, the telluride 4 is dimerized via Te···F secondary bonds and 5 adopts a tetrameric structure containing a central Ag4 ring. Furthermore the preparation of C5Me5P(H)RF (2) is described.
