Abstract
In the asymmetric unit of the title polymeric compound, [Co(C8H4O4)(C5H5N)2]n, there are two crystallographically independent CoII atoms, each of which is six-coordinated in a distorted octahedral geometry by four O atoms from benzenedicarboxylate anions and two N atoms from pyridine ligands. The benzenedicarboxylate dianions bridge the CoII atoms into a tape running along the b axis. C—H⋯O hydrogen bonds are observed in the tape and between the tapes.
