In the title compound, [Co(C12H12O4)(C5H5N)2]n, the CoII cation is coordinated by four O atoms from three 5-tert-butylbenzene-1,3-dicarboxylate anions and two N atoms from pyridine molecules in a distorted octahedral geometry. One carboxylate group of the anionic ligand chelates a CoII cation while another carboxylate group bridges two CoII cations, resulting in a polymeric layer parallel to (101). Weak C—HO hydrogen bonds occur between adjacent polymeric layers. In the crystal, one of pyridine molecules is equally disordered over two positions.
