Abstract

Isatin (L1) and N-methylisatin (L2) β-thiosemicarbazones react in ethanol with Cu(II) chloride and bromide in the presence of sulfanilamide (Streptocid, Sf1), N-acetylsulfanilamide (Sulfacyl, Sf2), Norsulfazole (Sf3), Aethazolum (Sf4), and Sulfadimesine (Sf5) to form coordination compounds Cu(Sf1–5)L1–2X2 · nH2O (X = Cl, Br; n = 2–5). All the complexes have a monomeric structure. Thiosemicarbazones L1 and L2 in these complexes are tridentate O,N,S ligands, and sulfanilamides Sf1–5 are monodentate ligands. Thermolysis of the substances involves the steps of dehydration (70–95°C) and complete decomposition (410–530°C).
