INVESTIGATION OF SOME PHYSICOCHEMICAL PROPERTIES OF 4-NITROCINNAMATES OF LANTHANIDES(III)
Lanthanide(III) 4-nitrocinnamates were synthesized as polycrystalline hydrated solids with the general formulae: Ln(C9H6NO4)3OH2O (where Ln = lanthanons (without Ce(III)), n=1 for La, Pr-Tb and n=2 for Dy-Lu). The complexes were characterized by elemental analysis, FTIR spectroscopy, magnetic and th...
