In the title compound, C(23)H(24)NO(4) (+)·Br(-), the butyl chain is disordered between two conformations; the occupancies refined to 0.735 (7) and 0.265 (7). The dihedral angle between the naphthalene ring system and the phenyl ring is 11.6 (2)°. In the crystal structure, the cations are packed via π-π inter-actions into stacks propagating in the [010] direction. Weak inter-molecular C-H⋯O and C-H⋯Br hydrogen bonds contribute further to the crystal packing stability.
在标题化合物C(23)H(24)NO(4)(+)·Br(-)中，丁基链在两种构象之间无序；占有率精修为0.735 (7)和0.265 (7)。萘环系统与苯环之间的二面角为11.6 (2)°。在晶体结构中，阳离子通过π-π相互作用堆积成沿[010]方向延伸的堆积柱。弱分子间C-H⋯O和C-H⋯Br氢键进一步有助于晶体堆积稳定性。
