The synthesis of two thiosemicarbazone derivatised ligands (L1 and L2) was achieved by reacting 1-(2-pyridinyl)ethanone hydrazone with benzoyl or pivaloyl isothiocyanate. Mononuclear complexes of nickel (II), copper (II), and zinc (II) with these ligands were synthesized and characterized using various techniques. The solid-state molecular structures of eight examples were successfully determined by single crystal X-ray diffraction.
The synthesis of two thiosemicarbazone derivatised ligands (L1 and L2) was accomplished via the reaction of 1-(2-pyridinyl)ethanone hydrazone and either benzoyl or pivaloyl isothiocyanate. A range of Ni(II), Cu(II) and Zn (II) mononuclear complexes of these thiosemicarbazone ligands have been synthesized providing insight on the reactivity of the ligands. These complexes (1-12) have been characterized by high resolution mass spectrometry, IR, UV-vis., 1H and 13C NMR spectroscopies, elemental analysis and magnetic measurements. The solid-state molecular structures of eight examples were successfully determined by single crystal X-ray diffraction.
