Triazidotris[μ-2-(2-pyridyl)ethanolato]dicobalt(II) acetonitrile monosolvate

In the title compound, [Co(2)(C(7)H(8)NO)(3)(N(3))(3)]·CH(3)CN, the two Co(II) ions in the dinuclear complex have different coordination environments, both in a distorted octa­hedral geometry. One Co(II) atom is coordinated by three O atoms from the three 2-hy­droxy­ethyl­pyridine (HEP) bridging ligands, two N atoms from two HEP ligands and one azido ligand, while the other Co(II) atom is coordinated by the same three O atoms, one N atom from an HEP ligand and two azido ligands. Weak inter­molecular C—H⋯N hydrogen bonds link the dinuclear complexes into corrugated layers parallel to the bc plane. These layers are further packed with the formation of channels propagating in [010] and filled with the disordered [in a ratio 0.691 (13):0.309 (13)] acetonitrile solvate mol­ecules.
