Abstract: | The present work is concentrated on the studies of two novel
semicarbazones, di-2-pyridyl ketone-N4-phenyl-3-semicarbazone (HL1) and
quinoline-2-carboxaldehyde-N4-phenyl-3-semicarbazone (HL2). The compositions
of these semicarbazones were determined by the CHN analyses. For the
characterization of these compounds we have used IR, UV and NMR spectral
studies. The molecular structure of quinoline-2-carboxaldehyde-N4-phenyl-3-
semicarbazone (HL2) was obtained by single crystal X-ray diffraction studies.
Also, we have synthesized Zn(II), Cd(II), Cu(II), Ni(II), Co(II) and Mn(II)
complexes of these semicarbazones, HL1 and HL2. These complexes were
characterized by various spectroscopic techniques, magnetic and conductivity
studies. We could isolate single crystals of some Zn(II) and Cd(II) compounds
suitable for X-ray diffraction studies. For other complexes we could not isolate
single crystals of good quality for single crystal X-ray diffraction studies. |
