Structural and spectral studies on manganese(II) complexes of di-2-pyridyl ketone N(4)-methyl and N(4)-ethyl thiosemicarbazones

Four manganese(II) complexes of two N(4)-substituted thiosemicarbazones from di-2-pyridyl ketone were synthesized and physico-chemically characterized by means of partial elemental analyses, molar conductance measurements, electronic, infrared and EPR spectral studies. The crystal structure of [Mn(DpyMeTsc)2] was established by single crystal X-ray diffraction studies. The compound crystallizes into a monoclinic lattice with P21/n space group.
