Title: Comparison of the X-ray crystal structures of the sodium and potassium 2,4,6-tris(trifluoromethyl)phenoxides (RO<sup>–</sup>) and 2,4,6-tris(trifluoromethyl)benzenethiolates (RS<sup>–</sup>); [Na(OR)(thf)<sub>2</sub>]<sub>2</sub>, [K(OR)(thf)<sub>2</sub>(µ-thf)]<sub>2</sub>, [Na(SR)(thf)<sub>2</sub>·0.25thf]<sub>x</sub>and [K(SR)(thf)]<sub>x</sub>(thf = tetrahydrofuran)
Abstract:[Na(OR)(thf)2]21, [K(OR)(thf)2(µ-thf)]22, [Na(SR)(thf)2·0.25thf]x3 and [K(SR)-(thf)]x4 were formed by the reaction of the appropriate combinations of 2,4,6-tris(trifluoromethyl)phenol (ROH) or 2,4,6-t...[Na(OR)(thf)2]21, [K(OR)(thf)2(µ-thf)]22, [Na(SR)(thf)2·0.25thf]x3 and [K(SR)-(thf)]x4 were formed by the reaction of the appropriate combinations of 2,4,6-tris(trifluoromethyl)phenol (ROH) or 2,4,6-tris(trifluorornethyl)benzenethiol (RSH) with NaH or KH; compounds 1-4 have been characterised by NMR spectrosccpy and single crystal X-ray structure analysis, both phenoxides being dimeric whereas two distinct polymeric structural types are observed for the thiolates.Read More
