catena-Poly[[(1,10-phenanthroline)cobalt(II)]-di-μ-azido]

Abstract

In the crystal structure of the binuclear title complex, [Co(N(3))(2)(C(12)H(8)N(2))](n), each Co(II) cation is coordinated by two N atoms from one chelating 1,10-phenanthroline ligand and four azide ligands in a slightly distorted octa-hedral coordination. The two Co(II) cations of the binuclear complex are related by an inversion centre and are bridged by two symmetry-related azide ligands in both μ(1,1) and μ(1,3) modes. The μ(1,3) bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the μ(1,1) bridging mode is responsible for the formation of the binuclear Co(II) complex.
