在标题化合物C32 H26 BN 5或[（C14 H11 N5）B（C6 H5）3]中，B原子近似为四面体配位。重氮单元处于反式构象，对于芳族偶氮化合物，反式构象通常比顺式构象更稳定。晶体结构具有非常弱的C-H π相互作用。杂环的中心苯环与端环之间的二面角分别为62.64 °、73.54 °和61.60°。
In the title compound, C32H26BN5 or [(C14H11N5)B(C6H5)3], the B atom is approximately tetrahedrally coordinated. The diazo unit is in a trans conformation, which is generally more stable than a cis one for aromatic azo compounds. The crystal structure features very weak C—H⋯π interactions. The dihedral angles between the central benzene ring and the terminal rings in the heterocycle are 62.64, 73.54 and 61.60°.
