Özet

13,14-bis(Hydroxyimino)-4,7-bis(ferrocenylmethyl)-2,3,4,5,6,7,8,9-octahydrobenzo[k]-4, 7-diaza-1, 10-dithiacyclodocine[13,14-g]-quinoxaline (H2L) has been prepared from (E,E)-dichloroglyoxime and 12,13-diamino-4,7-bis(ferrocenylmethyl)-2,3,4,5,6,7,8,9-octahydrobenzo[k]-4,7-diaza-1,10-dithiacyclododecine which was synthesized froin 12,13-dinitro-4,7-bis(ferrocenylmethyl)-2,3,4,5,6,7,8,9-octhydrobenzo[k]4,7-diaza-1,10-dithia cyclododecine. Mononuclear nickel(II) and copper(II) complexes of H2L have a metal-ligand ratio of 1:2 and the ligand coordinates through two nitrogen atoms, as do most (E,E)-dioximes. The homotrinuclear [Cu(L)(2)Cu-2(dipy)(2)](NO3)(2) compound coordinates to the other two copper(II) ions through deprotonated oximate oxygens and two 2,2'-dipyrdyl as an end-cap ligand to yield the trinuclear structure. Tiie ligands and its complexes have been characterized on the basis of H-1, C-13 NMR, IR and MS spectroscopy and elemental analyses.
