In the title polymer, Co(3)(C(6)H(8)O(4))(3)(C(19)H(12)N(4))(2), two adipate dianions (C(6)H(8)O(4) (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-tetra-azacyclo-penta-[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-H⋯O hydrogen bonds.
在标题聚合物[Co₃(C₆H₈O₄)₃(C₁₉H₁₂N₄)₂]ₙ中，两个己二酸二阴离子（C₆H₈O₄²⁻）占据一般位置，另外两个位于不同的反演中心。处于一般位置的两个己二酸二阴离子通过其四个氧原子与五个由2-苯基-1H-1,3,7,8-四氮杂环戊并[1]菲螯合的Co(II)离子相连，而处于特殊位置的两个则仅与四个Co(II)离子相连。在三个Co原子中，两个被氮杂环螯合；第三个与六个氧原子相连。二阴离子的键合模式产生了三维网络结构；该网络通过N-H⋯O氢键进一步巩固。
