title: Poly[(3-nitro-benzoato)(μ(3)-1,2,4-triazolato)cobalt(II)].
abstract: In the title compound, [Co(C(2)H(2)N(3))(C(7)H(4)NO(4))](n), the Co(II) atom is five-coordinated by three triazolate ligands and one bidentate 3-nitro-benzoate anion in a distorted trigonal-bipyramidal geometry. The triazolate ligand bridges the Co(II) atoms, generating a two-dimensional net parallel to the ab plane, in which both the Co(II) atom and the triazolate ligand act as three-connected nodes. Two weak inter-molecular C-H⋯O hydrogen bonds connect the nets.
