The novel (E,E)-dioxime, 5,6:11,12:17,18-tribenzo-2,3-bis(hydroxyimino)-7,16-dithia-9, 14-dioxo-1,4,10,13-tetraazacyclooctadecane (H2L) has been synthesized by reacting (E,E)-dichloroglyoxime (2) with 2,3:8,9:14,15-tribenzo-4,13-di-thia-6,11-dioxa-1,7,10,16-tetraazahexzadecane (3), prepared by the reaction of N,N'-bis(chloroacetyl)-1, 2-phenylene-diamine (1) with 2-aminothiophenol. Mononuclear complexes (4, 5) of this ligand have been synthesized by reacting the vie-dioxime (H2L) with K2PtCl4 and NiCl2.6H(2)O, respectively. Heterotrinuclear complexes (6) and (7) have been prepared by the reaction of (4) and (5) mononuclear complexes with [Cu(MeCN)(4)]PF6. The structures of the vie-dioxime and its mono and trinuclear complexes were identified by elemental analysis, H-1- and C-13-n.m.r, i.r. and m.s. data.
