In the title complex, [Co(CN)(2)(C(18)H(18)N(4))]PF(6), the Co(III) atom together with one of the pyridyl rings and two cyanide anions are located on a mirror plane, while the P atom is located on an inversion centre. The Co(III) atom exhibits an octa-hedral geometry, coordinated by four N atoms from the tris-(2-pyridyl-meth-yl)amine ligand with an average Co-N distance of 1.953 (2) Å, and two cyanide C atoms with an average Co-C distance of 1.895 (2) Å. The crystal packing is stabilized by inter-molecular C-H⋯N and C-H⋯F inter-actions.
在标题配合物[Co(CN)₂(C₁₈H₁₈N₄)]PF₆中,Co(III)原子与其中一个吡啶环和两个氰根阴离子位于一个镜面平面上,而P原子位于一个对称中心上。Co(III)原子呈现八面体几何构型,由三(2 - 吡啶基甲基)胺配体的四个N原子配位,平均Co - N距离为1.953(2) Å,以及两个氰根C原子配位,平均Co - C距离为1.895(2) Å。晶体堆积通过分子间C - H⋯N和C - H⋯F相互作用得以稳定。
