## Abstract The complex Eu(btfa)~3~ (phen) (btfa=4,4,4‐trifluoro‐1‐phenyl‐1, 3‐butanedione, phen = 1,10‐phenanthroline) has been prepared and characterized by elemental analysis, IR and UV spectroscopies. The crystal and molecular structures of the complex have been determined by X‐ray diffraction

## Phosphorescence decay has been measured at liquid helium tcmpcrntures for 2,2'dipyridyl, l,lO-phennntllroline and their tris and bis compleses with rhodium(lI1). The decay for the free lignnds and bis complcscs is exponential with lifetimes shorter than those measured at 77°K. The decay for th
