Thiosemicarbazide and 4-phenylthiosemicarbazide react in ethanol with 2,4-pentanedione in the presence of manganese, cobalt, nickel, copper, and zinc acetates hydrates and streptamin (Sf1), sulfaethidole (Sf 2), and sulfadimidine (Sf3) to form coordination compounds of the composition M(Sf1-3)(L1-2)·nH2O (M = Mn, Co, Ni, Cu, Zn; H2L1 is 2,4-pentanedione bis-thiosemicarbazone, H2L2 is 2,4-pentanedione bis-4-phenylthiosemicarbazone; n = 0-6). All the complexes synthesized are monomeric. Thiosemicarbazones (H2L1 and H 2L2) behave as twice deprotonated S,N,N,S-tetradentate ligands, while sulfanylamides (Sf1-3) act as monodentate ones. Thermolysis of these substances proceeds through the stages of dehydration (65-95°C) and complete thermal decomposition (430-560°C). It is found that the complex [Cu(Sf2)(L1)]·4H2O in the concentration 10-5 M inhibits the growth and fission of 100% cancer cells of the human myeloid leukemia (HL-60). |
