Synthesis and spectroscopic studies on platinum(II) complexes of thiosemicarbazone derivatives of <i>p</i>-anisaldehyde, <i>p</i>-tolualdehyde and <i>p</i>-vanillin

1152-1156The platinum(II) complexes of thiosemicarbazone derivatives of p-anisaldehyde (ATSCH), p-tolualdehyde (TTSCH) and p-vanillin (VTSCH) have been prepared and characterized by analytical, molar conductance, infrared, electronic, 1H and 13C NMR spectral data. Thiosemicarbazones exist in thione form and coordinate through thiolato/thione sulphur and azomethine nitrogen. The chloro bridged dinuclear structures for [Pt(ATSC)Cl]2 [Pt(TTSC)Cl]2 and [Pt(VTSC)Cl]2 having four coordinate platinum(II) centres and square planar for [Pt(ATSCH)2]Cl2, [Pt(TTSCH)2]Cl2 and (Pt(VTSCH)2Cl2 are suggested
