A new Hg-metallated biSchiff base ((E)-3-(1,5-dimethyl-3-oxo-2-phenyl-2,3- dihydro-1H-pyrazol-4-ylimino)-2-oxoindolin-1-yl((E)-3-(2-methyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-3-ylimino)-2- oxoindolin-1-yl)mercury (Hg(L<sub>I<\/sub>)<sub>2<\/sub>) was synthesized by condensation reaction of bis(2,3-dioxoindolin-1-yl) mercury(II) (Hg(isatin)2) with 4-aminoantipyrine(4-AAP). Reaction of L<sub>I<\/sub>H with Pt(II) and Cu(II) complexes in basic medium led to binding of the metal ions at N-1 atom of isatin ring while reaction of L<sub>I<\/sub>H and L<sub>II<\/sub>\u00a0with metal salts in neutral medium resulted in the formation of metal complexes where the metal ion is coordinated to carbonyl and azomethine groups of the two ligands. The metal complexes were characterized and their structures were suggested depending on CHNM and thermal analysis, FTIR and electronic spectra, magnetic susceptibility as well as conductivity measurements. The structures of the Ni(II), Pt(II) and Hg(II) complexes were further supported by NMR spectroscopy.<\/p><\/div><div class=\"item abstract\"><div><h3 class=\"label\">How to Cite this paper?<\/h3><div class=\"csl-entry\"><p><strong>APA-7 Style<\/strong><br \/>Abdulghani, A.J., Ahmed, Z.Z.
