The title complex, [Co(C(15)H(12)N(3)O(2)S)(2)], consists of an octahedrally coordinated Co(II) ion, with two crystallographically independent 1,4-dibenzoylthiosemicarbazidate ligands in a tridentate mer coordination [Co-O = 2.064 (3)-2.132 (3) A and Co-N = 2.037 (3)-2.043 (3) A]. There are intermolecular N-H...S hydrogen bonds involving one ligand and strong pi-pi stacking interactions involving the other ligand, resulting in a three-dimensional supramolecular framework. The hydrogen bonds and pi-pi interactions, as well as different intramolecular aryl-benzamide H-C...H(-N) distances, give rise to a difference in conformation between the two ligands.
标题配合物[Co(C₁₅H₁₂N₃O₂S)₂]由一个八面体配位的Co(II)离子组成，有两个晶体学独立的1,4 - 二苯甲酰硫代氨基脲配体以三齿面式配位[Co - O = 2.064(3) - 2.132(3) Å且Co - N = 2.037(3) - 2.043(3) Å]。存在涉及一个配体的分子间N - H...S氢键以及涉及另一个配体的强π - π堆积相互作用，形成三维超分子框架。氢键和π - π相互作用，以及不同的分子内芳基 - 苯甲酰胺H - C...H(-N)距离，导致两个配体之间构象存在差异。
