Crystal structures, spectroscopic properties of new cobalt(II), nickel(II), zinc(II) and palladium(II) complexes derived from 2-acetyl-5-chloro thiophene thiosemicarbazone: Anticancer evaluation

The reactions of cobalt(II), nickel(II), zinc(II) chlorides and [Pd(DMSO)2Cl2] with 2-acetyl-5-chloro-thiophene thiosemicarbazone (HL) leads to the formation of a series of new complexes: [CoCl2(S-HL)2], 1; [Ni(N,S-L)2], 2 [ZnCl2(S-HL)2], 3 and [PdCl2(N,S-HL)], 4. All the complexes have been charact...
