The title compound, C26H25N3, crystallizes with four independent mol-ecules, 1-4, in the asymmetric unit of the triclinic unit cell. The allyl substituents on the imidazole rings adopt similar conformations in all four mol-ecules. The imadazole and the 4-and 5-substituted phenyl rings of two pairs of molecules in the asymmetric unit stack parallel to (110). In contrast, the dimethyl-aniline systems in these pairs of mol-ecules are almost normal to one another, with dihedral angles of 85.84 (10) and 85.65 (10)° between the benzene rings of the two dimethyl-aniline fragments of mol-ecules 1 and 2, and 3 and 4, respectively. The crystal structure features an extensive series of C-H⋯π inter-actions that link the mol-ecules into undulating rows along the c axis. The crystal studied was a pseudo-merohedral twin with twin law [-100, 0-10, 111] and the BASF parameter refined to 0.513 (3).
标题化合物C26H25N3在三斜晶胞的不对称单元中以四个独立分子(1 - 4)结晶。咪唑环上的烯丙基取代基在所有四个分子中具有相似的构象。不对称单元中两对分子的咪唑环以及4 - 和5 - 取代的苯环平行于(110)堆积。相比之下,这两对分子中的二甲基苯胺体系几乎相互垂直,分子1和2以及3和4的两个二甲基苯胺片段的苯环之间的二面角分别为85.84 (10)°和85.65 (10)°。晶体结构具有一系列广泛的C - H⋯π相互作用,这些相互作用将分子沿c轴连接成起伏的行。所研究的晶体是具有孪晶定律[-100, 0 - 10, 111]的假半面体孪晶,BASF参数精修为0.513 (3)。
