Template synthesis of two new glyoxime derivatives. Characterization and investigation of their complexes with Ni(II), Cu(II), and Co(II) metal ions

Two novel oximes containing di- and tetraoxime groups, dichloro-[N,N'-bis(2 -aminophenyl)diaminoglyoxime]nickel(II), [Ni(LH2)Cl-2], and {dichloro-[5,6: 11,12-dibenzo-2,3,8,9-tetra(hydroxyimino)-1,4,7,10-tetraazacyelododecane]}- nickel(II), [Ni(LH4)Cl-2], have been synthesized by the template condensat ion reaction of dichloro-[N,N'-bis-(1,2-diaminobenzene)]nickel(II) with ant i-dichloroglyoxime. Trinuclear complexes of [Ni(LH2)Cl-2] with Ni(II), Cu(I I) and Co(II) have been synthesized. A polynuclear complex of [Ni(LH4)Cl-2] with Ni(II) has been prepared. The structures of these novel oxime compoun ds are proposed on the basis of the elemental analyses, IR and UV-Visible s pectra and conductivity measurements. Conductivity measurements have shown that all complexes are non-electrolytes.
