Abstract: In the title compound, [Co(C6H5NO2)(NCS)(C6H4NO2)]n, the Co2+ cation is coordinated by one N and two O atoms of three bridging pyridine-4-carboxylate anions, one O atom of one zwitterionic pyridinium-4-carboxylate ligand and one terminal N-bonding thiocyanate anion within a distorted N2O3 trigonal bipyramid. The bridging coordination mode of the ligands leads to the formation of layers parallel to (-101). N-H...O hydrogen-bonding interactions within the layers and S...S contacts of 3.257 (3) Å between the layers lead to the cohesion of the structure.
