In the title quaternary ammonium salt, C55H61N4+·I-, all three N,N-dibenzylethanamine, -(CH2)2N(CH2C6H5)2, groups have different conformations. The N-C-C-N torsion angles are significantly different [89.86 (13), 162.61 (10) and 175.70 (10)°] and the dihedral angles between the phenyl rings in these groups are different as well [58.21 (4), 43.73 (4) and 76.72 (5)°]. In the crystal, the I- anions fill empty spaces between the bulky cations. The cations and anions are linked by weak C-HI interactions, forming a chain along .
