抄録

A crystal of 2,3-dimethyl-1-isopropylimidazolium bromide was prepared and its crystal structure determined at the orthorhombic space group Pnma with cell parameters a = 11.407(6), b = 7.157(4), c = 12.111(7)Å, Z = 4. Sandwiched structures were observed between the cations and the bromide anions. The π…Br and C-H…Br interactions contributed to stabilization of the crystal packing of the title compound.
