| Popis: | Polynitrile anions are known for their ability to combine with transition metals and co-ligands to form ternary systems. Here we report on the crystal structure of tris(2–2′-bipyridine)cobalt(II) bis(1,1,3,3-tetracyano-2-ethoxypropenide). In the title compound, [Co(C10H8N2)3](C9H5N4O)2, the tris(2,2′-bipyridine)cobalt(II) dication lies across a twofold rotation axes in the space group C2/c. The N atoms of the three bipyridine ligands form a distorted octahedron around the cobalt ion. All the N atoms of the polynitrile 1,1,3,3-tetracyano-2-ethoxypropenide anions participate in C—H⋯N hydrogen bonds ensuring crystal cohesion and forming a three-dimensional structure. The structure is further stabilized by C—H⋯π(cation) and anion⋯π(cation) interactions. |
