Synthesis, crystal structure and properties of bis-(iso-seleno-cyanato-κ<i>N</i>)tetra-kis-(pyridine-κ<i>N</i>)nickel(II).

ABSTRACT: The reaction of nickel chloride hexa-hydrate with potassium seleno-cyanate and pyridine in water leads to the formation of crystals of the title complex, [Ni(NCSe)₂(C₅H₅N)₄], which were characterized by single-crystal X-ray diffraction. Its crystal structure consists of discrete complexes, located on centers of inversion, in which the Ni cations are sixfold coordinated by two terminal N-bonded seleno-cyanate anions and four pyridine ligands within a slightly distorted octa-hedral coordination. In the crystal, the complexes are connected by weak C-H⋯Se inter-actions. PXRD investigations revealed that a pure crystalline phase has formed. In the IR and Raman spectra, the C-N stretching vibrations are observed at 2083 and 2079 cm^-1, respec
