I-aluminium chloride eyenziwe amakristalu namamolekyuli amanzi ayisithupha (AlCl3·6H2O): amakristalu angenambala kuya kophuzi, ancibilika kakhulu, akhipha intuthu encane emoyeni omanzi. Ngokungafani nosawoti ongenamanzi, akusona isivusamsebenzi se-Friedel-Crafts; i-ammonia ishiya i-aluminium hydroxide esixazululweni sayo.
