Two Zn(II) and Hg(II) bromide salts, [EMI]2[ZnBr4] (1) and [EMI][HgBr3] (2), have been synthesized under ionothermal conditions using 1-ethyl-3-methyl imidazolium bromide ([EMI]Br) as solvents. 1 consists of tetrahedral anion [ZnBr4]2− and 2 consists of 1D double chain locating in the cavities surrounded by [EMI]+ cations. Both compounds exhibit 3D supramolecular architectures organized by the C-H···Br hydrogen bondings and alkyl-alkyl interactions.

KEY WORDS: Crystal structure, 1-Ethyl-3-methyl imidazolium bromide, Ionothermal synthesis, Supramolecular organization
