K₂Hg₆Se₇, Na₂Hg₃S_2.51Se_1.49, K₂Hg₃S_1.03Se_2.97, and K₂Hg₃S_2.69Se_1.31 were prepared by ionothermal treatment of K₂Hg₂Se₃, Na₂HgSe₂, and K₂Hg₃Se₄, respectively, in a nonclassical hydrosulfide ionic liquid (EMIm)(SH). In contrast to their lighter congeners, the title compounds could so far not be synthesized by inorganic polychalcogenide salt flux techniques. The applied method hence mimics polychalcogenide flux conditions, while operating at much lower temperatures below the decomposition temperature of the ionic liquid. It might thus be viewed as a pseudo-flux approach.
