Abstract
Solid complexes of 3-acetyl- 1,5-diaryl and 3-cyano- 1,5-diaryl formaz ans were prepared and characterized by elemental analysis, IR, NMR, TG A and DTA analyses. Based on these studies, the suggested general form ula for the complexes is [M(HL)m(OH-)n or (NO3- or Cl-)x.(H2O)y or (C2 H5OH or DMSO)z, where HL = formazan M = Ce3+, Th4+, and UO22+, m = 1-2 , n = 0-3, x = 0-3, y = 0-4 and z = 0-3. The metal ions are expected t o have coordination numbers 6-8.
