pubmed:abstractText |
The crystal structure of [Ni(L(III))(2)] (1), where HL(III)=thiophene-2-carbaldehyde thiosemicarbazone, consists of monomeric entities where the nickel(II) ions exhibit distorted square planar geometry. The two bidentate thiosemicarbazone ligands are centrosymmetric. C...S van der Waals' links and nonbonded intramolecular interactions are present in the structure. The biological activity of 1 is compared to that of the free ligand, and the cobalt(III) (2) and copper(II) (3) derivatives. The observed order of cytotoxicity against melanoma B16F10 and Friend erythroleukemia cells is: 1< or =ligand<2<3. A structure-activity correlation using Extended-Hückel MO calculations is described.
