In the crystal structure of the title Co(II) complex, [Co(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the metal centre is located on an inversion center and is coordinated by two 4-formyl-benzoate (FOB), two diethyl-nicotinamide (DENA) ligands and two water mol-ecules in a slightly distorted CoO(4)N(2) octa-hedral geometry. In the crystal structure, O-H⋯O hydrogen bonds link the mol-ecules into infinite chains. π-π contacts between the parallel pyridine rings of neighboring DENA ligands [centroid-centroid distance = 3.652 (3) Å] further stabilize the crystal structure.
在标题钴（II）配合物[Co(C₈H₅O₃)₂(C₁₀H₁₄N₂O)₂(H₂O)₂]的晶体结构中，金属中心位于一个对称中心上，由两个4-甲酰基苯甲酸酯（FOB）、两个二乙烟酰胺（DENA）配体和两个水分子以略微扭曲的CoO₄N₂八面体几何构型配位。在晶体结构中，O-H⋯O氢键将分子连接成无限链。相邻DENA配体平行吡啶环之间的π-π接触[质心-质心距离 = 3.652 (3) Å]进一步稳定了晶体结构。
