[(18-C-6)K][Hg(Rf)2X] (Rf = CF 3, C6F5; X = Br, I) are prepared from the reactions of Hg(Rf)2 with [(18-C-6)K]X in CH 2Cl2 or H2O in good yields. The trifluoromethyl compounds [(18-C-6)K][Hg(CF3)2X] crystallize isotypically in the monoclinic space group P21; the acentric space group is proved by measurements of the optical SHG effect. [(18-C-6)K][Hg(C6F5)2Br] crystallizes in the monoclinic space group P21/n and [(18-C-6)K][Hg(C6F 5)2I] in the triclinic space group P1?. The anions of the crystalline compounds are monomeric with a T-shaped surrounding of the Hg atoms. Mass spectra and the thermal stability of the mercurates are described.
