The asymmetric unit of the title compound, C(27)H(36)N(4), contains two independent mol-ecules. Except for the atoms of the decyl chain, the non-H atoms of each mol-ecule are approximately coplanar (r.m.s. deviations = 0.075 and 0.164 Å) and the -CH(2)CH(2)CH(2)- link connecting the two benzimidazolyl fused-ring systems is slightly opened up at the middle C atom. The decyl substituent adopts an extended zigzag conformation in both mol-ecules. In the crystal, adjacent mol-ecules inter-act by N-H⋯N hydrogen bonds, generating a chain parallel to the c axis.
标题化合物C(27)H(36)N(4)的不对称单元包含两个独立分子。除癸基链的原子外，每个分子的非H原子近似共面（均方根偏差分别为0.075和0.164 Å），连接两个苯并咪唑稠环系统的-CH(2)CH(2)CH(2)-链在中间C原子处略有张开。癸基取代基在两个分子中均采用伸展的锯齿构象。在晶体中，相邻分子通过N-H⋯N氢键相互作用，形成平行于c轴的链。
