2-[3-(1H-Benzimidazol-2-yl)propyl]-1-decyl-1H-benzimidazole

Abstract

The asymmetric unit of the title compound, C 27H 36N 4, contains two independent molecules. Except for the atoms of the decyl chain, the non-H atoms of each molecule are approximately coplanar (r.m.s. deviations = 0.075 and 0.164 Å) and the -CH 2CH 2CH 2- link connecting the two benzimidazolyl fusedring systems is slightly opened up at the middle C atom. The decyl substituent adopts an extended zigzag conformation in both molecules. In the crystal, adjacent molecules interact by N - H⋯N hydrogen bonds, generating a chain parallel to the c axis.
