Abstract: In the title polymer, [Co₃(C₆H₈O₄)₃(C₁₉H₁₂N₄)₂]_n, two adipate dianions (C₆H₈O₄^2-) occupy general positions and two are situated on different inversion centres. The two on general positions bind through their four O atoms to five 2-phenyl-1H-1,3,7,8-tetraazacyclopenta[l]phenanthrene-chelated Co^II ions, whereas the two on special positions bind to only four. Of the three Co atoms, two are chelated by N-heterocycles; the third is bonded to six O atoms. The bonding mode of the dianion gives rise to a three-dimensional network structure; the network is further consolidated by N-HO hydrogen bonds.
