Abstract
Copper(II) and nickel(II) complexes with selected hylenebis(1-phenyl-3 -methyl-4-acylpyrazoloneimine) ligands were synthesised and characteri sed spectroscopically. Molar conductivity measurements for the complex es in DMF indicate that the complexes are neutral. The metals reacted with the Schiff bases in the metal:ligand mole ratio of 1:1 to form an hydrous complexes. Bands in the UV spectral region of the complexes we re due to pi-->pi transitions. A weak broad band due to d-d transitio n was observed in the visible region.
