Abstract: The tetracation of bis(2-ammonioethyl)piperazin-1,4-ium tetraperchlorate tetrahydrate, C₈H₂₄N₄⁴⁺·4ClO₄^-·4H₂O, lies over a center of symmetry and the piperazinyl ring adopts a chair conformation. Four ammonium N atoms, perchlorate anions and lattice water molecules are linked by hydrogen bonds into an infinite three-dimensional framework.
