Abstract: 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 interactions. The dihedral angles between the central benzene ring and the terminal rings in the heterocycle are 62.64, 73.54 and 61.60°.
