title: Poly[(μ3-pyridine-4-carboxyl-ato-κ(3) O:O':N)(pyridin-1-ium-4-carboxyl-ato-κO)(thio-cyanato-κN)cobalt(II)].
abstract: In the title compound, [Co(C6H5NO2)(NCS)(C6H4NO2)] n , the Co(2+) cation is coordinated by one N and two O atoms of three bridging pyridine-4-carboxyl-ate anions, one O atom of one zwitterionic pyridinium-4-carboxyl-ate ligand and one terminal N-bonding thio-cyanate 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 inter-actions within the layers and S⋯S contacts of 3.257 (3) Å between the layers lead to the cohesion of the structure.
