Synthesis and Characterization of 2-(Hydroxyimino)-1-(phenylpropylidene)thiocarbonohydrazide and its Metal Complexes with Co(II), Ni(II) and Cu(II) Ions

Synthesis and characterization of 2-(hydroxyimino)-1-(phenyl propylidene) thiocarbonohydrazide (called 'HPTCHOPD') was studied. The synthesized compound having the molecular formula C10 H13 N5OS, where in isonitrosopropiophenone is reacted with thiocarbonohydrazide in presence of sodium acetate in ethanol-water mixture. The yield which is comprises effecting the reaction in the presence of sodium acetate. Also the present work report a process for producing metal complexes having the formula ML 2 and (ML) 2Cl, wherein M is the divalent metal cation, like cobalt (Co +2 ), nickel (Ni +2 ) and copper (Cu +2 ). The compound HPTCHOPD is admixed with a basic divalent compound that is halide, mainly chloride of Co +2 , Ni +2 and Cu +2 in presence of methanol-water mixture. The metal complexes so produced are characterized on the basis of spectral, elemental and magnetic analysis; reveal interesting geometries and bonding features. The data suggested square planar geometry for Co +2 complex, a distorted tetrahedral/square planar-octahedral geometry for Ni +2 complex and a bridged structure for Cu +2 complex.
