The asymmetric unit of the title compound, C(27)H(20)N(2), contains two independent mol-ecules, A and B. In both mol-ecules, the N atom in the 1-position and the C atom in the 5-position are statistically disordered [as 0.571 (8):0.429 (8) in A and 0.736 (9):0.264 (9) in B]. The phenyl rings in the 1-, 2-, 4- and 5-positions in A are twisted from the central imidazole ring by 84.3 (2), 21.6 (2), 21.5 (2) and 75.7 (2)°, respectively. The corresponding dihedral angles in B are 85.5 (2), 3.8 (2), 2.4 (2) and 81.7 (2)°, respectively.
标题化合物C(27)H(20)N(2)的不对称单元包含两个独立分子，A和B。在这两个分子中，1位的N原子和5位的C原子存在统计无序[在A中为0.571 (8):0.429 (8)，在B中为0.736 (9):0.264 (9)]。A中1、2、4和5位的苯环与中心咪唑环的扭转角分别为84.3 (2)、21.6 (2)、21.5 (2)和75.7 (2)°。B中相应的二面角分别为85.5 (2)、3.8 (2)、2.4 (2)和81.7 (2)°。
