Complex compounds of sulphates and chlorides of cobalt (II), nickel (II), copper (II), manganese (II), cadmium (II) and zinc with N, N-dimethylformamide, as well as mixed acidoligand complex compounds of cobalt (II), nickel (II), manganese (II) and copper (II) with N,N-dimethylformamide were synthesized. In order to study the rules of coordination of N,Ndimethylformamide and thiocyanate groups, IR spectra of synthesized complex compounds were studied. Based on the study of IR spectra, it was found that in all synthesized complex compounds, the coordination of the N,Ndimethylformamide molecule

The heterometallic optical complexes [Cu2Co(S,S(+)cpse)3(H2O)3]·4H2O (1) and [Cu2Ni(S,S(+)cpse)3(H2O)3]·10H2O (2) were obtained from the mononuclear copper(II) compound by the addition of nickel(II) or cobalt(II) chlorides, where (H2cpse) is the acetyl amino alcohol derivative N-[2-hydroxy-1(R)-methyl-2(R)-phenylethyl]-N-methylglycine. In comparison with the homotrinuclear copper(II) compound [Cu3(S,S(+)cpse)3(H2O)3]·8H2O reported previously, the substitution of a copper(II) atom by one cobalt(II) ion gave place to a heterotrinuclear compound1, which presents ferromagnetic-antiferromagnetic be

Abstract:

Metal complexes are currently potential therapeutic compounds. The acquisition of resistance by cancer cells or the effective elimination of cancer-affected cells necessitates a constant search for chemical compounds with specific biological activities. One alternative option is the transition metal complexes having potential as antitumor agents. Here, we present the current knowledge about the application of transition metal complexes bearing nickel(II), cobalt(II), copper(II), ruthenium(III), and ruthenium(IV). The cytotoxic properties of the above complexes causing apoptosis, autophagy, DNA
