[Uses]

Potassium trifluoromethanesulfonate is used in studies of mixed alkali effects and short range interactions in poly(ethylene oxide) electrolytes,1 and characteristics of the electrochemical behavior of glassy carbon in super-acid media.
[General Description]

Potassium trifluoromethanesulfonate (KOTf, potassium triflate) is the potassium salt of trifluoromethanesulphonic acid. It has been prepared by neutralizing a warm aqueous solution of trifluoromethanesulphonic acid with potassium carbonate. The structure of siloxane–poly(oxyethylene) hybrids doped with potassium triflate has been investigated.
[structure and hydrogen bonding]

According to the results of temperature dependent powder diffractometry potassium trifluoromethanesulfonate is dimorphic. The phase transition occurs between -63 degreesC and 45 degreesC. The low-temperature modification crystallizes monoclinic with a=10.300(3)Angstrom, b = 6.052(1) Angstrom, c = 14.710(4) Angstrom, beta =111.83(2)degrees (-120 degreesC) and the room-temperature modification with a=10.679(5) Angstrom, b=5.963(2)Angstrom, c=14.624(5)Angstrom, beta =111.57(3)degrees, Z=6, P2(1). According to single crystal structure determination, potassium trifluoromethanesulfonate consists of three different potassium-oxygen-coordination polyhedra, linked by sulfur atoms of the trifluoromethanesulfonate groups. This results in a channel structure with all lipophilic trifluoromethane groups pointing into these channels[1].
