In the title compound, [Co(C7H4ClO2)2(C5H5N)2(H2O)], the Co(II) atom is six-coordinated by three O atoms from a bidentate and a monodentate 4-chloro-benzoate ligand, two N atoms from two pyridine ligands and a water O atom, giving a distorted octa-hedral geometry. In the crystal, the complex mol-ecules are connected by O-H⋯O hydrogen bonds and π-π interactions between the benzene rings [centroid-centroid distance = 3.8924 (17) Å] into a chain along [010]. Between adjacent chains, π-π inter-actions occur between the pyridine rings [centroid-centroid distance = 3.898 (2) Å], giving an overall two-dimensional architecture.
在标题化合物[Co(C₇H₄ClO₂)₂(C₅H₅N)₂(H₂O)]中，Co(II)原子由一个双齿和一个单齿4-氯苯甲酸酯配体的三个O原子、两个吡啶配体的两个N原子以及一个水分子的O原子进行六配位，形成扭曲的八面体几何构型。在晶体中，配合物分子通过O—H⋯O氢键以及苯环之间的π-π相互作用[质心-质心距离 = 3.8924 (17) Å]沿[010]方向连接成链。在相邻链之间，吡啶环之间发生π-π相互作用[质心-质心距离 = 3.898 (2) Å]，形成整体的二维结构。
