Synthesis, crystal structure and thermal decomposition pathway of bis-(iso-seleno-cyanato-κN)tetra-kis-(pyridine-κN)manganese(II).

ABSTRACT: The reaction of MnCl₂·2H₂O with KSeCN and pyridine in water leads to the formation of the title complex, [Mn(NCSe)₂(C₅H₅N)₄], which is isotypic to its Fe, Co, Ni, Zn and Cd analogues. In its crystal structure, discrete complexes are observed that are located on centres of inversion. The Mn cations are octa-hedrally coordinated by four pyridine coligands and two seleno-cyanate anions that coordinate via the N atom to the metal centres to generate trans-MnN(s)₂N(p)₄ octa-hedra (s = seleno-cyanate and p = pyridine). In the extended structure, weak C-H⋯Se contacts are observed. Powder X-ray diffraction (PXRD) investigations prove that a pure sample was obtained and in the IR and Raman spectra,
