摘要：

The preparation, thermal stability, volatility and spectral characteristics of lanthanide(III) complexes formed from 1,1,1-trifluoromethyl-5,5-dimethyl-2,4-hexanedione (HPTA), 1,1,1-trifluoromethyl-4-phenyl-1,3-butanedione (HBTA) and 1,3-diphenyl-1,3-propanedione (HDBM) are described. Under the conditions (aqueous or aqueous ethanol solution) employed HPTA gives rise to tetrakis chelates, HBTA to (hydrated) tris chelates and HDBM to basic polymeric products. The tetrakis chelates M[Ln(PTA)4], where M+ is an alkali metal cation, are all volatile. However those with M+ Ph4As+ and M+ Et4N+ are non-volatile, although still of high thermal stability. © 1969.
