Chromium reaction with liquid ammonia

Aquopentammine- or acidopentamminechromium(III) salts have been prepared by the reaction of liquid ammonia with anhydrous chromium (III) chloride 1 by the oxidation... 

That the nature of the polytelluride solution plays an important role is also borne out by studies of the chromium-telluride system. If the polytel-lurides are prepared in situ by the reaction of elemental potassium with elemental tellurium in DMF, the products are considerably cleaner and can be obtained in higher yields than when the polytelluride source is a premade potassium salt, such as K2Te2 or K2Te3, It has been suggested that equilibria are occurring in the reaction flask. Pure Te2- and Te2- can be prepared in pure form in liquid ammonia, but there is no evidence for the formation of higher tellurides in the presence of alkali metal counter-...
