Abstract

Ligand resulted from reaction between diacetylmonooximethiocarbohydrazide and p-chlorobenzaldehyde have been synthesised and investigated for its coordinating properties for tripositive metal ions such as Nd(III), Dy(III), Sm(III), and Pr(III). All complexes prepared were of 1:1 electrolyte bichelated compounds and are characterized as seven coordinated geometries based on electronic spectrum and magnetic moment data. In FTIR spectra, through the nitrogen atom of azomethine and oximino groups, the prepared HDMTpCB ligand interacts with the central metal ions and functions as a bidentate ligand. For the Ln(III) complexes, the magnetic moments and electronic spectral data support seven coordinated geometry for these complexes. Additionally, using the X-ray diffraction method, the structure of the Ln(III) complexes has been established.
