Co(ii), Ni(ii) and Cu(ii) complexes with phenylthiazole and thiosemicarbazone-derived ligands: synthesis, structure and cytotoxic effects

“…Therefore, the lack of an additional phenyl ring and of the thiazole ring results in two important consequences: (i) the sulfur atom participates in the coordination of the metal ion, (ii) the lack of the thiazole ring allows for bigger conformational flexibility, as presented by a bigger value of the dihedral angle created between the N1 pyrazole and chelate rings. This is confirmed by the results obtained by Radosavljevic ´et al 34 for Cd 2 L 00 2 Cl 4 (L 00 = 3,5-dimethyl-1H-pyrazole-1-carbothioamide). They showed that the pyrazole and chelate rings remain coplanar with an angle of 19.8( 5 26 The mutual conformation of L 0 or L 00 ligands in complexes described by the 1 : 2 metal : pyrazole ligand stoichiometric ratio usually ranges from 50-601 in the reported structures.…”
