Hexamminechromium III Nitrate

Rollinson andBailar prepared hexamminechrOmium,(III) nitrate in low yield by treating anhydrous chromium (III) sulfate with liquid anunonia in the presence of ammonium nitrate. They also prepared the hexammine by dissolving chloropentamminechromium(III) nitrate in liquid ammonia containing a little sodium amide. The following procedure utilizes the observation of Rollinson and Bailar that sodium amide (a base in liquid ammonia) catalyzes the ammona-tion of the chloropentamminechromium(III) ion.
