The synthesis of the binuclear complex [(NH 3 )] CrOhCr(NH 3 ) 4 CH 2 CH 2 \documentclass{article}\pagestyle{empty}\begin{document}$ \mathop {\rm N}\limits^{(+)} $\end{document} H 3 6+ , which has been obtained in the form of the well crystallised hexachloride is described. On adding alkali (titration in a rapid flow apparatus) the OH‐bridge (pK = 6,36) is first deprotonated and the terminal ammonium group (pK = 8,42) afterwards. Both deprotonation products are blue and highly unstable, hydrolysing rapidly to the hydroxo‐erythro ion and ethylenediamine.
