【 摘 要 】

The asymmetric unit of the title compound, [Mn(NCS)2(C12H9NO)4], consists of one MnII cation located on a centre of inversion, one thio­cyanate anion and two 4-benzoyl­pyridine co-ligands. The MnII cation is octa­hedrally coordinated by two terminally N-bonded anionic ligands and four N-bonded 4-benzoyl­pyridine co-ligands within a slightly distorted octa­hedron. Individual complexes are linked by inter­molecular C—H⋯O hydrogen-bonding inter­actions into chains running along the c-axis direction. Simultaneous thermogravimetry and differential scanning calorimetry measurements reveal a decomposition in two separate steps, in each of which two co-ligands are removed. The compound obtained after the first step has the composition [Mn(NCS)2(C12H9NO)2] and is of unknown structure, before in the second step decomposition into [Mn(NCS)2] is observed. Magnetic susceptibility measurements show the MnII cations to be in the high-spin state, and that weak anti­ferromagnetic inter­actions between the complexes are present.
