Chromium ammonia
WebThe ammonia molecules are not stripped from the chromium, such that it forms green chromite-ion. Both of these final experiments show that the ammonium molecules are bound to the chromium atom very tightly. … WebElemental analysis confirms that the product is a chromium complex containing four carbonyl (CO) ligands and two ammonia ligands i.e. [Cr (CO)4 (NH3)2]. This complex can exist as two isomers where the ammonia ligands are either located cis or trans to one This problem has been solved!
