None:
The title compound, C(23)H(24)INOP(+)·C(24)H(20)B(-), was prepared by treatment of 3-amino-propyl triphenyl-phospho-nium bromide hydrogen bromide with p-nitro-phenyl iodo-acetate at 203 K. The asymmetric unit contains a single cation and anion, which are linked in the crystal by inter-molecular N-H⋯π and inversion-related R(2) (2)(14) C-H⋯O inter-actions, which combine to form chains of cations and anions along the c axis.
