Abstract

The reaction between manganese(II) acetate and two substituted thiosemicarbazones derived from di-2-pyridyl ketone (HL) in 1:2 molar ratio produces new complexes of general formula $[MnL_2]$. The thiosemicarbazone moiety in HL deprotonates and gets coordinated to Mn(II) through the azomethine nitrogen, one of the pyridyl nitrogens, and the thiolate sulfur in both the complexes. The crystal structure of $[MnL\frac{1}{2}]$ was established by single crystal X-ray diffraction and the compound crystallizes into a monoclinic lattice with $P2_1/c$ space group. Manganese(II) exists in a distorted octahedral geometry in the complexes.
