Abstract
The interaction of lanthanide nitrates (Ln–Nd, Sm, Dy and Er) and 1.10–phenantroline were studied and complexes of the general formulae Ln(NO3)3(C12H8N2)2 or Ln(NO3)3(o-fen)2. The complexes were characterized by elemental analyses (CHN), titration with EDTA, IR spectra and thermogravimetric analysis. X-ray powder patterns further indicated that the complexes are isomorphous having the same d -interplanar spacing.
