Praseodymium forms complexes easily with nitrogen and oxygen donor pyrazolines and also forms mixed ligand complexes with these pyrazolines and sulfur donor thio ligands such as dithiocarbamates and xanthates.

series of mixedligandcomplexes of Zn(II) of molecular formula Zn(C15H12N2OX)(C6H4OCHNY) where X= ‒H, ‒CH3, ‒OCH3, Cl, and Y=C7H7, C5H4N, C6H4NO2, (C15H12N2OX) = [3(2′hydroxyphenyl)-5-(4′-X-substituted phenyl) pyrazolines], and (C6H4OCHNY) = Schiff base have been synthesized. These complexes were prepared by reacting the solution of ZnCl2 in THF with sodium salts of Schiff base ligands. The resulting

Synthesis, physicochemical characterization, and biological activity of nanocomplexes of iron(III) of 3(2′-hydroxyphenyl)-5-(4-substituted phenyl) pyrazolines and dithiophosphoric acid
Complexes of iron(III) with dithiophosphoric acid and 3(2'-hydroxy phenyl)-5-(4-substituted phenyl) pyrazolines, [Fe(C6O14O2PS2)(2)(C15H12N2OX)], and [Fe(C6O14O2PS2)(C15H12N2OX) 2], where (C6O14O2PS2H) = dithiophosphoric acid, (C15H13N2OX) = deprotonated 3(2'-hydroxy phenyl)-5-(4-substituted phenyl) pyrazolines (X= H, CH3, OCH3, Cl), have been synthesized. These complexes have been physicochemically characterized by elemental analysis (C, H, N, S, Cl, and Fe), magnetic moment data, thermogravimetric analysis, molar conductance, cyclic voltammetry, and spectral analysis (UV-visible, IR, and Fast atom bombardment mass spectrometry). Scanning electron microscopy, TEM, and PXRD have been carried out for powdered samples, which show nanometric particles of these derivatives. Antibacterial and antifungal potential of free pyrazoline and iron(III) complexes have been evaluated.
