In the title complex, [Co(C(10)H(11)N(2)O(2))(2)(C(5)H(5)N)(2)], the Co(II) atom lies on a centre of symmetry and adopts a distorted cis-CoO(2)N(4) octa-hedral geometry. The two acetone salicyloylhydrazone ligands are deprotonated and act as N,O-bidentate monoanionic ligands, forming the equatorial plane, while the axial positions are occupied by two N atoms of two pyridine mol-ecules. The complex presents O-H⋯N and C-H⋯N intra-molecular hydrogen bonds. Inter-molecular C-H⋯N and C-H⋯O inter-actions are also present in the crystal.
在标题配合物[Co(C₁₀H₁₁N₂O₂)₂(C₅H₅N)₂]中，Co(II)原子位于对称中心，采用扭曲的顺式CoO₂N₄八面体几何构型。两个丙酮水杨酰腙配体去质子化，作为N,O-双齿单阴离子配体，形成赤道平面，而轴向位置由两个吡啶分子的两个N原子占据。该配合物存在分子内O-H⋯N和C-H⋯N氢键。晶体中还存在分子间C-H⋯N和C-H⋯O相互作用。
