Terbium acetate is a convenient source of terbium ions, and may be used for the preparation of compounds like terbium phthalocyanine. It dissolves readily in water to form a colorless solution, but is far less soluble in ethanol. However, crystals of terbium acetate will disintegrate in minutes if left in ethanol.
Terbium acetate is expected to form a coordination polymer if heated in methanol.
Terbium acetate is a colorless solid which forms triclinic crystals by evaporation, which can become quite large if left to grow for a long period of time. It is far less hygroscopic than the corresponding halides. It is also highly magnetic and can be lifted quite easily with a neodymium magnet.
Terbium acetate fluoresces bright green when exposed to ultraviolet light.
Terbium acetate is a difficult compound to purchase, due to the low availability of terbium itself. Most sources are extremely overpriced.
Terbium acetate can be prepared by dissolving terbium metal, terbium(III) oxide, terbium hydroxide, or terbium carbonate in dilute acetic acid. Acetic acid that is too concentrated will cause terbium acetate to precipitate out. If this occurs, adding more water redissolves the material.
- Make terbium salts
- Make terbium phthalocyanine
Terbium acetate shows moderate toxicity and has no known biological role, though it may stimulate plant growth.
Terbium(III) acetate can be stored in a vial or other sealed container.
Terbium acetate is too damn expensive to throw away, so you should probably recycle it.
