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.
For metal-organic frameworks composed of cobalt cations and 5-tert-butylbenzene-1,3-dicarboxylate ligands without additional bridging ligands, see: Chen et al. (2011); Du et al. (2009); Ma et al. (2009); Qin & Ju (2010). For a copper(II) complex with 5-tert-butylbenzene-1,3-dicarboxylate ligand, see: Li & Zhou (2010).
