The title compound, C5H16N22+. 2Cl(-), was isolated as a byproduct from the
reaction between trimethylethylenediamine and germanium tetrachloride in t
he presence of triethylamine. The asymmetric unit contains two cations, one
in the gauche and the other in the trans conformation; these conformations
are stabilized by hydrogen-bonding interactions between the N-H moieties a
nd the chloride anions.
