-pyrazine-2N:N')cobalt(II)]Abstract: In the crystal structure of the title compound, [Co(NCO)2(C4H4N2)2]n, the Co(II) cation is coordinated by four N-bonded pyrazine ligands and two N-bonded cyanate anions in a slightly distorted octahedral geometry. The crystal structure consists of -N:N' pyrazine-bridged cobalt cyanate chains; these are further linked by additional -N:N'-bridging pyrazine ligands into layers, which are stacked perpendicular to the crystallographic a axis. The C and O atoms in both crystallographic independent cyanate anions are disordered in two orientations and were refined using a split model with site occupation factor ratios of 0.75/0.25 and 0.7/0.3.
