Abstract
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 thio-cyanate anion and two 4-benzoyl-pyridine co-ligands. The Mn(II) cation is octa-hedrally coordinated by two terminally N-bonded anionic ligands and four N-bonded 4-benzoyl-pyridine co-ligands within a slightly distorted octa-hedron. Individual complexes are linked by inter-molecular C-H⋯O hydrogen-bonding inter-actions 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 anti-ferromagnetic inter-actions between the complexes are present.
