The levels of soil parameters and selected heavy metals around a solid waste dumpsite receiving untreated wastes from all sources and a control site within Port Harcourt, Nigeria have been examined. Top soil (0–15 cm) and sediment samples were coll

La(III), Y(III) and Fe(III) complexes of 4-acylbis(l-phenyl-3-methyl-pyrazolone-5) were synthesised and characterised spectroscopically. Y(III) and Fe(III) reacted with the ligands in the metal:lig...

Thorium tetrakis (1-phenyl-3-methyl-4-acylpyrazol-5-onoates) have been synthesised and characterized spectros-copically using UV, IR and 13C NMR spectroscopy. IR spectral data showed a stereochemically differing CO-Th bonding system present in some o

Synthesis, electronic, infrared and NMR spectral studies were carried out on a series of 4-acyl-3-methyl-1-phenylpyrazolone-5 complexes of lead(II). They showed that both Pb-O and Pb-N bonds were present in the complexes. Subsequently, the complexes

The synthesis of 4-phenylacetyl-3-methyl-1-phenylpyrazolone-5 is reported. Analysis of its IR and NMR spectral data has revealed that the ligand is bidentate and has spectral properties that resemble neither those of the 4-benzoyl, 4-acetyl derivativ
