ABSTRACT:
A novel Ni(II), Pd(II) and Pt(II) complexes of Isonitrosopropiophenone thiocarbonohydrzone benzaldehydes derived from N”-[(1Z,2E)-(hydroxyimino)-1-phenylpropylidene]thiocarbonohydrazide (HTIPP)and substituted benzaldehydes, have been synthesized and studied. Six new ligands are reported herein using two electron withdrawing (-Cl, -NO2) and two electron donating (-OH,-OCH3) substituents benzaldehyde and HTIPP. Their structures have been discussed on the basis of spectral, magnetic and powdered X-ray crystallography studies. The dimeric nature of the complexes supported by molecular weight determinations by Rast method. The result so obtained suggest binuclear distorted octahedral geometry for Ni(II) complexes, while mononuclear square planar geometry for Pd(II) and Pt(II) complexes. The room temperature magnetic susceptibility measurements reveals that antiferromagnetic interactions exists between the high spin Ni(II) ions within the dinuclear unit. The powdered X-ray crystallography study reveals orthorhombic crystal system for Ni(II) complexes.
