Tetra­kis(4-benzoyl­pyridine-κN)bis­(iso­thio­cyanato-κN)manganese(II)

The asymmetric unit of the title compound, [Mn(NCS)(2)(C(12)H(9)NO)(4)], consists of one Mn(II) cation located on a centre of inversion, one thio­cyanate anion and two 4-benzoyl­pyridine co-ligands. The Mn(II) 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)(C(12)H(9)NO)(2)] and is of unknown structure, before in the second step decomposition into [Mn(NCS)(2)] is observed. Magnetic susceptibility measurements show the Mn(II) cations to be in the high-spin state, and that weak anti­ferromagnetic inter­actions between the complexes are present.
