But in practice, someone attempting to predictthe properties of compounds can occasionally be frustrated by various complicating factors.For instance, the nitrite ligand is presented as having a high field strength, but that is only whenit is the nitrogen of the nitrite that is coordinating to the metal center. Nitrite is also capable ofbinding to the metal center through an oxygen, and when this happens, nitrite is a low fieldstrength ligand. Furthermore, many metals initially precipitate as simple ionic salts before theyhave a chance to form more soluble complex ions.
