Complexes of 1,8-bis(hydrazidomethylsulfonyl)octane and 1,10-bis(hydrazidomethylsulfonyl)decane with copper(II)

Abstract

© 2020 Kazan Federal University. All rights reserved. 1,8-bis(hydrazidomethylsulfonyl)octane and 1,10-bis(hydrazidomethylsulfonyl)decane differ by hydrocarbon spacer length, solubility in water, and polymerization tendencies. They and their amides are known to be new antitubercular agents. The substances act as polydentate ligands; in the pH range of 4.5–5.0 and with copper(II), they form cationic mono- and binuclear complexes. Preparatively isolated copper complexes with each of the two compounds have different compositions, which also differ from the composition of complexes in the solution.
