The Synthesis and Complex Formation of Dibenzo e,k-2,3-Bis(Hydroxyimino)-1,4-Diaza-7,10-Dithia-2,3,8,9-Tetrahydrocyclododecine

摘要

Dibenzo e,k-2,3-bis(hydroxyimino)-1,4-diaza-7,10-dithia-2,3,8,9-tetrahydrocyclododecine (LH4) has been prepared from cyanogendi-N-oxine and 1,2-bis(o-aminophenylthio)ethane (APT). The structure of thisvic-dioxime has been determined asanti-isomer according to its1H n.m.r, and i,r spectral data. The trinuclear complexes of this compound, (LH)2M3, where M = Cu(II), Ni(II) and Pd(II), have been obtained. In these complexes the metals coordinate to the sulfur atoms of thioethers and the nitrogen atoms of the aza and oxime groups. Also mononuclear complexes of thisvic-dioxime, the using Ni(II), Co(II), Cu(II) and UO2(VI), have been isolated. The structures of these complexes and thevic-dioxime were identified by using1H n.m.r, i,r, and uv-visible spectral data and elemental analysis.
