摘要

The title compound (C18H26N6Cl2) crystallizes in monoclinic space group P2(1)/c with a = 14.867(4) angstrom, b = 7.758(2) angstrom, c = 9.671(3) angstrom, beta = 108.78(1)degrees, V = 1056.0(5) angstrom(3), Z = 2, D-cal = 1.250 Mg/m(3) at T = 293 K. The structure was solved by direct methods and refined by full-matrix least-squares procedures to final R = 0.0650 and wR = 0.1719 using 2493 reflections. The imidazole ring is planar and the n-butyl chain adopts an extended conformation. The molecules in the crystal are stabilized by N-H center dot center dot center dot N type of intermolecular hydrogen bondings in addition to van der Waals forces.
