Abstract
The low temperature fluorescence spectrum of the microcrystalline solid complex Eu(HMPA) 4(ClO 4) 3 has been analyzed under high resolution. The observed splittings of the 5D 0 → 7F 1,2 transitions are consistent with a S 4 site symmetry at the Eu(III) site in this complex. Thus the chromophoric group in this complex is the octacoordinated Eu(O) 8 unit; the coordinating oxygen atoms being provided by two bidentate perchlorate and four symmetry related P → O groups of the HMPA ligands. The infrared, Raman and the conductivity data agree with the formulation [Eu(HMPA) 4(ClO 4) 2](ClO 4) for the complex and complement the octacoordinated structure with S 4 symmetry predicted from the splittings of the fluorescent lines. A genuine charge transfer band has been observed at 37.04 kK with a δ(−) = 4.8 kK.
