Abstract:In this study, proton transfer salts (H2Etpip)(Hssa), (H2HOEtpip)(Hssa) and (HAcpip)(H2ssa), have been obtained by reactions between 1-ethylpiperazine (Etpip), 1-(2-hydroxyethyl)piperazine (HOEtpip) and 1-acetylpiperazine (Acpip) and 5-sulfosalicylic acid (H3ssa). Also, Cu(II) complexes of proton transfer salts (H2Etpip)[Cu(Hssa)2]•5H2O, (H2HOEtpip)[Cu(Hssa)2]•5H2O and (H2Acpip)[Cu(Hssa)2]•5H2O) have been synthesized. The structures of proton transfer salts have been proposed by using FT-IR, 1 H and 13 C NMR s… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
