Synthesis and Crystal Structure of an Infinite 1D Zigzag Chain Compound (dimbH+)(ClO4-) and Its Comparison with (dimb)·2H2O (dimb =1,3-Di(imidazol-1-ylmethyl)-5-methylbenzene)

摘要

A new imidazolium compound, C15H17N4(ClO4, was prepared from a flexible bidentate ligand of 1,3-di(imidazol-1-ylmethyl)-5-methylbenzene, and characterized by X-ray analysis. It is of orthorhombic, space group Pnma with a = 8.182(2), b = 12.874(3), c = 15.611(4) （A。）, V = 1644.4(7) （A。）3, Dc = 1.425 g/cm3, Z = 4, Mr = 352.78, μ(MoKα) = 0.944 mm－1, F(000) = 736, S = 1.036, the final R = 0.0521 and wR = 0.1187 for 1128 observed reflections (I > 2σ(I)). An infinite one-dimensional zigzag chain is formed by N-H…N hydrogen bonding interactions between the imidazolium salt cations.
