IN THE TITLE COMPOUND [SYSTEMATIC NAME: 13,15-dibromo-3,10-dithia-tricyclo-[10.2.2.2(5,8)]octa-deca-1(14),5,7,12,15,17-hexa-ene-6-carbonitrile], C(17)H(13)Br(2)NS(2), the mean planes of the benzene rings are almost parallel, making a dihedral angle of 1.1 (2)°, and the distance between the ring centroids is 3.294 (3) Å, which is shorter than the normal packing distance of aromatic rings (about 3.4 Å), indicating a strong π-π inter-action. The S atom of one bridging chain is disorderd over two positions with site occupancies of 0.605 (4) and 0.395 (4) for the major and minor components, respectively.
在标题化合物[系统名称：13,15-二溴-3,10-二硫杂-三环-[10.2.2.2(5,8)]十四碳-1(14),5,7,12,15,17-六烯-6-腈]，C(17)H(13)Br(2)NS(2)中，苯环的平均平面几乎平行，二面角为1.1(2)°，环心之间的距离为3.294(3)Å，这比芳香环的正常堆积距离(约3.4Å)短，表明存在强π-π相互作用。一条桥连链的S原子在两个位置上无序，主要和次要组分的占位分别为0.605(4)和0.395(4)。
