New palladium(II) formamidine complexes: Preparation, characterization, theoretical calculations and cytotoxic activity

Binary Pd(II) formamidine complexes formulated as [Pd(L1−4)Cl2] where L = formamidine ligands, were synthesized and characterized. The complexes are diamagnetic and the electronic spectral data showed the peaks due to square planar Pd(II) complexes. The structures are geometrically optimized and the energy parameters are calculated. The complexes have noticeable cytotoxicity. Molecular electronic potential (MEP) of complex (1) (isocontour value = 0.02). Hydrogen atoms are omitted for simplicity.121
