Chemical compound
Terbium acetylacetonate is a coordination compound with the formula Tb(C5 H7 O2 )3 . This anhydrous acetylacetonate complex is often discussed but unlikely to exist per se. The 8-coordinated dihydrate Tb(C5 H7 O2 )3 (H2 O)2 is a more plausible formula based on the behavior of other lanthanide acetylacetonates. The dihydrate has been characterized by X-ray crystallography .[1] [2] Upon attempted dehydration by heating under vacuum, other hydrated lanthanide tris(acetylacetonate) complexes decompose to give oxo-clusters.[3] The complex can be prepared from terbium salts, acetylacetone, and a base such as ammonia.
3 NH3 + 3 Hacac + Tb(NO3 )3 → Tb(acac)3 + 3 NH4 NO3
It reacts with 5-[(2-thiophene methylene)amino]-8-hydroxyquinoline (L) by heating in acetonitrile /dichloromethane solution to obtain light yellow [Tb(acac)4 (L)6 (μ3-OH)2 ]·CH3 CN crystals.[4] It can be used in the preparation of some optical materials.[5] [6] [7]
