Summary: | The alkylammonium chain of the dication in the title mitochondrially targeted (5-ammoniopentyl)triphenylphosphonium dibromide ethanol solvate, C23H28NP2+·2Br−·C2H6O, 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 C32(6) chains along the b axis, with secondary C—H...Br and C—H...O interactions cross-linking the chains.
