Abstract

In the crystal structure of the binuclear title complex, [Co(N3)2(C12H8N2)]n, each CoII cation is coordinated by two N atoms from one chelating 1,10-phenanthroline ligand and four azide ligands in a slightly distorted octa­hedral coordination. The two CoII cations of the binuclear complex are related by an inversion centre and are bridged by two symmetry-related azide ligands in both μ1,1 and μ1,3 modes. The μ1,3 bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the μ1,1 bridging mode is responsible for the formation of the binuclear CoII complex.

Highlights

  • N atoms from one chelating 1,10-phenanthroline ligand and four azide ligands in a slightly distorted octahedral coordination

  • The two CoII cations of the binuclear complex are related by an inversion centre and are bridged by two symmetryrelated azide ligands in both 1,1 and 1,3 modes

  • The 1,3 bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the 1,1 bridging mode is responsible for the formation of the binuclear CoII complex

R factor = 0.052; wR factor = 0.101; data-to-parameter ratio = 14.9. N atoms from one chelating 1,10-phenanthroline ligand and four azide ligands in a slightly distorted octahedral coordination. The two CoII cations of the binuclear complex are related by an inversion centre and are bridged by two symmetryrelated azide ligands in both 1,1 and 1,3 modes. The 1,3 bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the 1,1 bridging mode is responsible for the formation of the binuclear CoII complex
