Synthesis, Structure, and Biological Activity of Coordination Compounds of Cobaltmethylene]hydrazine Carbothioamides

4-(2-Methoxyphenyl)-, 4-(3-methoxyphenyl)-, and 4-(4-methoxyphenyl)-2-[(5-nitrofuryl)methylene]-hydrazine carboxamide ([HL.sup.1-3]) react with hydrates of cobalt (nickel, copper) chloride (nitrate, acetate) with the formation of the M[([HL.sup.1-3]).sub.2][X.sub.2] (M = [Co.sup.2+], [Ni.sup.2+], [Cu.sup.2+]; X = [Cl.sup.-], N[O.sub.3.sup.-]) and M[([L.sup.1-3]).sub.2] (M = [Ni.sup.2+], [Cu.sup.2+]) coordination compounds. Structure of the obtained compounds has been studied by means of X-ray diffraction analysis. Their antimicrobial and antifungal activity towards a series of Staphylococcus aureus, Escherichia coli, and yeast-like fungi standard strains has been investigated.
