Abstract

Six new Co(II) and Co(III) complexes (1–6) of di-2-pyridyl ketone N(4)-cyclohexyl thiosemicarbazone $(HL^1)$ and di-2-pyridyl ketoneN(4)-phenyl thiosemicarbazone $(HL^2)$ have been synthesized and spectrochemically characterized. $HL^1$ is newly synthesized and has been structurally characterized by single crystal X-ray diffraction studies, while $HL^2$ has been previously reported. $HL^1$ crystallizes into a monoclinic lattice with the space group $P2_1$. The complexes are characterized by magnetic, EPR, NMR and other spectroscopic studies. The EPR spectra of the paramagnetic complexes reveal axial features with eight hyperfine lines clearly resolved in the perpendicular region.
