“…The Schiff base ligands are important chelating agents for their versatility in the transition metal chemistry (Attari et al, 1997;Dey and Nandi, 1996;Joshi et al, 1999;Kuhn et al, 1997;Maurya and Jayaswal, 1997;Men'shikov et al, 1999;Shah, 1985a, 1985b;Rai et al, 1999;Rana and Shah, 1982;Satpathy and Sahoo, 1971;Soni and Shah, 1985;Tangadurai and Natarajan, 2000;Thaker and Desai, 1996;Xinde et al, 1996). Among them are the aromatic mono and diamine derivatives of hetrocyclic b-diketones, which are quite interesting for their chelating behavior.…”

Oxovanadium(IV), Cr(III), Fe(III), Fe(II), Ni(II), Cu(II), Zn(II) and UO 2 (VI) chelates of an ONNO donor Schiff base ligand derived from 4-butyryl-1,3diphenyl-2-pyrozolin-5-one and urea were prepared and characterized by elemental analyses, thermogravimatric analyses (TGA), conductivity, magnetic susceptibility, infrared and electronic spectral measurements. The molar conductivities of the chelates show that they are non-electrolytes, except the Cr(III) and Fe(III) chelates, which are 1:1 electrolytes. The ONNO donor set of the ligand is inferred from its infrared and NMR spectral studies. The magnetic moments and electronic spectral data suggest a distorted tetragonal geometry for the Cu(II) chelate and an octahedral geometry for the rest of the chelates.
