Abstract : The crystal and molecular structure of 2-ethylbenzimidazole has been determined by three dimensional single-crystal x-ray analysis. The compound crystallizes in the monoclinic space group P2 sub 1/c with a = 20.762(4)A, b = 8.095(1)A, c = 9.951(2)A, and beta = 100.06(2)A. Least-squares refinement of 696 reflections resulted in a final R factor of 0.072. There are two crystallographically independent molecules in the unit cell. The benzimidazole ring is planar. Molecules are linked together by NH. . . .N hydrogen bonds to form chains parallel to the c axis.
