Chapter 2 _. M_ _ up 1. Quinoline-2-c arbaldehyde N(4),N(4)-(butane-1,4-diyl) thiosemicarbazone (HE) 2. 2-Benzoylpyridine-N(4),N(4)-(butane-1,4-diyl) thiosemicarbazone (HL*') \N \N s / /N HL7 8 Scheme 2.2. Thiosemicarbazone ligands with general atom numbering scheme. The synthesis of H;L1 was reported [10] meagerly, without any spectral studies. Synthesis and crystal structure of HQL2 have been reported simultaneously [4,1]]. The spectral data for HQLZ was reinvestigated here for a comparison with that of other compounds, as there were contradictions in the two reports [4,] l]. Also there is a report of synthesis of I-l;L5 [4] but without much study. However, there are no further reports of their coordination chemistry. The other two carbohydrazones and thiocarbohydrazone H;L3 are new ligands. We have reported the synthesis and structure of the ligand HQL4 [l6]. Synthesis and structural and spectral studies of thiosemicarbazone HL8 and its iron(lIl) [I7], Cu(ll) [18] and Mn(Il) complexes [19] have been reported from our laboratory. But their coordination towards other transition metals like Ni(Il) haven’t reported. However. the ligand HL7 is a newly synthesized one. The synthesis and studies of these thiosemicarbazone ligands are found relevant as a supporting study. For studying their coordinating properties and for a comparison with that of their higher homologue thiocarbohydrazone ligands also prompted us to study these thiosemicarbazones. 38
