Structural Studies on 3-Acetyl-1,5-Diaryl and 3-Cyano-1,5-Diaryl Formazan Chelates with Cerium(III), Thorium(IV) and Uranium(VI)

Article abstract of DOI:10.1007/BF00817298

Solid complexes of 3-acetyl-1,5-diaryl and 3-cyano-1,5-diaryl formazans were prepared and characterized by elemental analysis, IR, NMR, TGA and DTA analyses.Based on these studies, the suggested general formula for the complexes is -)n or (NO3^- or Cl^-)x*(H2O)y or (C2H5OH 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 to have coordination numbers 6-8. - Keywords: Complexes of 3-acetyl and 3-cyano formazans; Ce(III); Th(IV); U(VI)
