metal-organic compounds
The title compound, [Co(NO3)2(C11H7NS)2], has twofold axial symmetry. The central cobalt ion is coordinated by four O atoms of two nitrate anions and two N atoms of two 2-[2-(2-thienyl)ethynyl]pyridine ligands in a distorted octahedral geometry. The non-coordinating thiophene moiety is disordered over two overlapping orientations. Short bifurcated C—HO interactions link the molecules into an infinite chain parallel to the c axis.
