(5-Ammonio­pent­yl)triphenyl­phospho­nium dibromide ethanol solvate

The alkyl­ammonium chain of the dication in the title mitochondrially targeted (5-ammonio­pent­yl)triphenyl­­phos­pho­nium dibromide ethanol solvate, C(23)H(28)NP(2+)·2Br(−)·C(2)H(6)O, is almost planar (r.m.s deviation = 0.0716 Å for all non-H atoms) and in the extended form, maximizing the P⋯N distance [7.716 (2) Å]. The ions and solvent are linked within the crystal by N—H⋯Br, N—H⋯O and O—H⋯Br hydrogen-bonding inter­actions, forming C (3) (2)(6) chains along the b axis, with secondary C—H⋯Br and C—H⋯O inter­actions cross-linking the chains.
