Description
Summary:The novel ( E , E )-dioxime, 5,6:17,18-dibenzo-11,12-(4'-nitrobenzo)-2,3-bis(hydroxyimino)-7,16-dithia-10,13-dioxa-1,4-diazacyclooctadecane) ( H 2 L ), has been synthesized from reaction of ( E , E )-dichloroglyoxime ( 1 ) with 2,3:14,15-dibenzo 8,9-(4'-nitrobenzo)-4,13-dithia-7,10-dioxa-1,16-diazahegzadecane ( 2 ). The mononuclear Co(III) complex ( 4 ) of this dioxime was prepared by oxidation of the cobalt (II) complex. The -capped Co(III) complex ( 5 ) was synthesized by using a precursor Co(III) complex and boron trifluoride dietherate. The heterotrinuclear complexes ( 6 ) and ( 7 ) were prepared by reaction of ( 5 ) with NiCl 2 ·6H 2 O and CdCl 2 ·H 2 O, respectively. In addition, the homotrinuclear Cu(II) complex ( 8 ), has also been prepared by the reaction of this dioxime with CuCl 2 ·H 2 O. The structures of the dioxime and its complexes were identified by using elemental analysis, 1 H- and 13 C-NMR, IR, and mass spectral data.
