摘要：

EMIF.HF, 1-ethyl-3-methylimidazolium bifluoride, has been obtained by eliminating HF from a room temperature molten salt EM1F.2.3HF at around 400 K. EM1F.HF crystallizes in space group P2(1)/m with a = 7.281(1) Angstrom, b = 6.762(1) Angstrom, c = 8.403(1) Angstrom, beta = 107.26(1)degrees, V = 395.09(18) Angstrom(3), Z = 2 at room temperature. The cations are stacked in pillars via the hydrogen bonding between the C4 proton and the ring pi-electrons of the adjacent cation. The cations and the anions coupled by strong hydrogen bondings are co-planar. (C) 2002 Editions scientifiques et medicales Elsevier SAS. All rights reserved.
