| Abstract: | The ligand
3,8-dimethyl-5,6-benzo-4,7-diazadeca-3,7-diene-2,9-dione dioxime [(DOH)-bzo]
has been synthesized by the condensation of o-phneylenediamine
with diacetyl monoxime in a 1:2 mole ratio. It has been isolated in the solid
state and characterized by CHN data, and IR and NMR spectral studies. Six
coordinate Co (II) complex, four coordinate square planar Ni (II) complex and
five coordinate square pyramidal Cu (II) complex are synthesized by the
reaction of the respective metal chlorides. All these complexes are characterized
by infrared, electronic spectroscopy and conductivity measurements. Indirect
evidence for the formation of intra-molecular hydrogen bond in these complexes
is obtained by replacing the hydrogen bonded proton by BF2 group by
treating the complex [Cu (DO) (DOH) bzo) Cl] with BF3OEt2. |
