Abstract

Graphical abstract: Two pyridyl containing thiosemicarbazone ligands have been explored in coordination chemistry with Ni(II), Cu(II) and Zn(II) salts. The resultant complexes have been characterised using a range of techniques and the structural properties elucidated. Abstract: 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., 1 H and 13 C NMR spectroscopies, elemental analysis and magnetic measurements. The solid-state molecular structures of eight examples were successfully determined by single crystal X-ray diffraction.
